Incoming Sharepoint Mail: External/Internal Domain Environment

We have setup Incoming Sharepoint 2010 Mail both on Sharepoint side and on the Exchange 2007 side (Send Connector setup). And we have no problem delivering mail from Exchange to Sharepoint.
We have an External/Internal Domain setup.
Our Windows DNS does not own the “A” record for our External domain Name @external.Domain.com.
All mailboxes/mail-enabled contacts/UDG’s/USGS are stamped with our External domain Name: @external.Domain.com because within Exchange an accepted domain (Internal Relay Type) was created for @external.Domain.com.
Sharepoint is part of our Internal Windows domain. Sharepoint mail-enabled contacts are created as
[email protected]
Per Incoming mail technote: we created Active Directory Org Unit for Share Point mail-enabled contacts. These contacts replicated to Exchange Recipient Management Console and then of course
to the Outlook Global Address List; however, the contacts are not a routable address because they are stamped @windows.Internal.Domain.com. If we add @external.Domain.com which is a routable address, mail is delivered to the Sharepoint Site.
Q. One thing we do not want is within our Outlook Global Address List, to show two SMTP domain names, i.e., @windows.Internal.Domain.com and @external.Domain.com this would be
too confusing for our users. Also changing each mail-enabled contact to the routable address (@external.Domain.com would be a nightmare. Any suggestions or assistance would be greatly appreciated?

It doesn't need to be a nightmare, you simply have to create a Recipient Update Policy and apply it to the OU containing your contacts/DLs. You also need to configure SharePoint to use external.domain.com instead of the internal domain.
See http://thesharepointfarm.com/2013/02/a-practical-guide-to-implementing-incoming-email-using-the-sharepoint-directory-management-service/
for more info on how this is done.

How to block incoming mail with internal domain as sender

Hi all,
Ironport accept incoming mail to internal domains defined in the RAT without verify the sender domain is the same internal domain.
To avoid this I have used a message filter to drop those mails. I can't use the bounce command to avoid to be considered a spammer.
Is there a way to reject those mails with a 5xx error message?
Thanks in advance.
Regards,
Andrea

Securegroup,
jloehler is absolutely correct, when I configure appliances (personally I use a 1 listener config) I set the Default Mailflow Policy to Use the Exception Table ("On") and insure that all incoming mail policies (anything with the ACCEPT action) is set to "Use Default" for this parameter. Then I double check to insure that the RELAY policy is set to "Off" because you don't want to reject outbound messages due to the Exception Table.
Once I've verified that the RELAY is off and Inbound policies are "On" I then populate my exception table with all the internal domains and specify the reject action. Now a quick take away is that the Exception Table only performs the rejection based on the SMTP MAIL FROM not the "From:" header internal to the message itself.
Now with all that said it never fails that there is some internal group that uses 3rd party marketing which spoofs the internal domains so I usually create a new incoming mail flow policy with the Exception Table turned "Off" and create a Sender Group call DOMAINSPOOFLIST which are IPs and Domain names that I allow to spoof internal e-mail addresses with the new mail policy assigned to it.
And that's it.
Sincerely,

Best practices of having a different external/internal domain

In the midst of migrating from a joint Windows/Mac server environment to a completely Apple one. Previously, DNS was hosted on the Windows machine using the companyname.local internal domain. When we set up the Apple server, our Apple contact created a new internal domain, called companyname.ltd. (Supposedly there was some conflict in having a 10.5 server be part of a .local domain - either way it was no worries either way.) Companyname.net is our website.
The goal now is to have the Leopard server run everything - DNS, Kerio mailserver, website, the works. In setting up the DNS on the Mac server this go around, we were advised to just use companyname.net as the internal domain name instead of .ltd or .local or something like that. I happen to like having a separate local domain just for clarity's sake - users know if they are internal/external, but supposedly the Kerio setup would respond much better to just the one companyname.net.
So after all that - what's the best practice of what I should do? Is it ok to have companyname.net be the local domain, even when companyname.net is also the address to our external website? Or should the local domain be something different from that public URL? Or does it really not matter one way or the other? I've been running companyname.net as the local domain for a week or so now with pretty much no issues, I'd just hate to hit a point where something breaks long term because of an initial setup mixup.
Thanks in advance for any advice you all can offer!

Part of this is personal preference, but there are some technical elements to it, too.
You may find that your decision is swayed by the number of mobile users in your network. If your internal machines are all stationary then it doesn't matter if they're configured for companyname.local (or any other internal-only domain), but if you're a mobile user (e.g. on a laptop that you take to/from work/home/clients/starbucks, etc.) then you'll find it a huge PITA to have to reconfigure things like your mail client to get mail from mail.companyname.local when you're in the office but mail.companyname.net when you're outside.
For this reason we opted to use the same domain name internally as well as externally. Everyone can set their mail client (and other apps) to use one hostname and DNS controls where they go - e.g. if they're in the office or on VPN, the office DNS server hands out the internal address of the mail server, but if they're remote they get the public address.
For the most part, users don't know the difference - most of them wouldn't know how to tell anyway - and using one domain name puts the onus on the network administrator to make sure it's correct which IMHO certainly raises the chance of it working correctly when compared to hoping/expecting/praying that all company employees understand your network and know which server name to use when.
Now one of the downsides of this is that you need to maintain two copies of your companyname.net domain zone data - one for the internal view and one for external (but that's not much more effort than maintaining companyname.net and companyname.local) and make sure you edit the right one.
It also means you cannot use Apple's Server Admin to manage your DNS on a single machine - Server Admin only understands one view (either internal or external, but not both at the same time). If you have two DNS servers (one for public use and one for internal-only use) then that's not so much of an issue.
Of course, you can always drive DNS manually by editing the zone files directly.

Mail server is too slow to deliver the mail to internal domain

Hi,
My mail server faster enough to send the mails to other domains, but when i try to send mail to my own domain it too slow some time it take 30 t0 40 minutes to deliver the mail.
Please help
Thanks,

You should use statspack to check what are the main waits.
Some indicators to check :
- too many fts/excessive IO => check sql statements (missing index, wrong where clause)
- explain plan for most important queries : using cbo or rbo ? If cbo, statistics should be up to date. If rbo, check acces path.
-excessive logfile switch (> 5 per hour) : increase logfile or disable logging
- undo waits => not enough rollback segments (if you don't set AUM)
- data waits => alter initrans, pctfree, pctused
- too many chaining rows => rebuild set of datas or rebuild table
- too many levels in indexes => rebuild index
- excessive parsing : use bind variable or alter parameter cursor_sharing
- too many sort on disks => increase sort_area_size and create others temporary tablespace on separate disks
- too many blocks reads for a row => db_block_size too few or too many chaining rows
- too many lru contention => increase latches
- OS swapping/paging ?
Too improve performance :
- alter and tune some parameters : optimizer_mode, sort_area_size, shared_pool_size, optimizer_index_cost_adj, db_file_multiblock_read_count...
- keep most useful packages in memory
- gather regularly statistics (if using cbo)
How do your users access to the db ?

Accessing Sharepoint 2013 externally for domain users and customers

Just an FYI I am not a SP administrator by any means but have be tasked with taking over this project and could use some assistance.
Sharepoint 2013 is working fine internally. Users access the site and login with their domain credentials. Our client is moving one of their departments to another building down the street and we'd like them to be able to access local resources without the
use of another server or site to site vpn or standard vpn.
My question is, how do we make Sharepoint accessible outside of their local network?
If we open up a port on the router and have it forward all request to Sharepoint server will we be able to access it?
Also, how will they authenticating with the Sharepoint Server? Do they use the same user credentials?
I forgot to mention this is Sharepoint 2013 Enterprise Edition. We are also using Project Server 2013 as well.
Thanks in Advance

Hi 3s1k,
According to your description, my understanding is that you want to access the SharePoint site from Internet.
You need to first ensure that you enable Anonymous Access for your web application. You'll then need to set up DNS for the domain you own to point to your web front end server (or virtual IP if it's load balanced). Then set up the appropraite IIS bindings
for the web application, and finally you'll need to extend your web application to an Internet Zone and give it the appropriate domain name.

Server 2012 - Can't access external website from internal domain with same name. Tried everything.

Hello All.
I have read loads of forums and tried numerous fixes and configurations, but nothing seems to work and I am extremely frustrated at this point.
I have a client where I setup Server 2012 Standard with Exchange 2013. After reading best practice documentation for DNS naming and reasons not to use ".LOCAL" I opted to use ".com.na" in which case the Internal Domain Name and Internet
Website now has the same name.
When attempting to open the extarnal website eg. "www.company.com.na" from a client PC within the internal "company.com.na" Domain, I keep getting error "403 - Forbidden: Access is denied. You do not have permission to view this
directory or page using the credentials that you supplied."
I should also mention, the website is hosted by an ISP and not locally.
I added a "www" Host record in the Forward Lookup Zone, I have added the url and ip address to the Hosts file on a client pc (Windows 7) and even tried setting up Split-Brains DNS. Nothing seems to work.
Running a Tracert takes me to the correct public ip address of the website, but I keep getting this 403 error.
I am so sick and tired of this issue that iI am at the point of backing up the Exchange and re-rolling the entire server with the ".local" DNS domain name. I have a mirror setup in a VMWare environment and simply using "rendom" to rename
the domain seems to cause new issues with Exchange connectivity.
Any pointers and help will be greatly appreciated.
Thanks in advance.

I opted to use ".com.na" in which case the Internal Domain Name and Internet Website
now has the same name.
This ends up with a split-DNS stup for internal and external resolution which requires extra administration tasks and attention from the administrators.
When attempting to open the extarnal website eg. "www.company.com.na" from a client PC within the internal "company.com.na" Domain, I keep getting error "403 - Forbidden: Access is denied. You do not have permission to view
this directory or page using the credentials that you supplied."
I should also mention, the website is hosted by an ISP and not locally.
I added a "www" Host record in the Forward Lookup Zone, I have added the url and ip address to the Hosts file on a client pc (Windows 7) and even tried setting up Split-Brains DNS. Nothing seems to work.
Running a Tracert takes me to the correct public ip address of the website, but I keep getting this 403 error.
This means that you are able to reach the Website but it is responding with the access denied error message. That should be checked on the middleware level so if this is IIS running then I would recommend asking them in IIS forum: http://forums.iis.net/
If this is a Website that is completely managed by your ISP then I would recommend checking with them.

Outlook 2013 people pane is not showing any items for internal domain users. External contacts works fine

I have recently purchase a new PC which has Windows 8.1, and Outlook 2013, connected to an exchange 2010 SP3 RU4 server.
In the People pane, the for External clients, then this box populates correctly, but for internal domain users, it shows "There are no items to show in this view"
On my OLD PC using XP, and Outlook 2010, connected to the SAME account, then people pane shows correctly for all users.
Any help appreciated
regards
Chris

Hi Chris,
I have checked in my Windows 8 and Outlook 2013 with Exchange 2010 SP3 RU4 environment. There are three folders listed under My Contact in my People pane:
Contacts: The contacts which we added and saved
manually before.
Lync Contacts: The contacts we added in Lync.
Suggested contacts folder: Automatically
keeps track of everyone you send a message to, but isn’t in your Outlook contacts. Please note that it is different from Auto-Complete List.
Therefore, I suppose that the meaning of “but for internal domain users, it shows ‘There are no items to show in this view’ ” is that there is no contacts in the
Contacts folder. Is it right? If I misunderstand, please point it out. And we need to add and save users manually in this folder.
Thanks,

Follow up - DNS (internal domain has same name as external website)

Hi,
I am following up with on previous blog entry about resolving an domain internal name to an external website found here:
https://social.technet.microsoft.com/Forums/windowsserver/en-US/4d97325b-ff3a-4f46-ba6e-dc3f4ff978e1/dns-internal-domain-has-same-name-as-external-website
On October 30, 2014
HayashiTech provided a response suggesting the use of netsh interface portproxy on the DC's to resolve this issue. There has been no feedback to this suggestion and I am very curious what opinions are out there for this suggestion as it appears to be the
best option provided yet.
Thank you in advance as well for all the great guidance I have found provided by Ace and his followers.

Interesting question. I've not seen that solution before, but having done a test on my lab setup it certainly seems to work as expected. Eg, using :
netsh interface portproxy add v4tov4 listenport=80 listenaddress=dc1.abc.com connectport=80 connectaddress=www.abc.com
on my DC where I've setup a working external domain name with the www record pointing to the website, and the non-www record pointing to the DC, requests to the non-www address are successfully being redirected to the www address (after confirming it didn't
happen prior to adding the portproxy).
So on the face of it that does look like a workable solution. I haven't used it myself in anger obviously, but the two downsides I can think of immediately to this solution are :
1) This operates as a proxy, so unlike the IIS method that Ace mentioned where it would tell the client to go to the www address instead (so the client connects direct), this method keeps your DC acting as a middle man, eg all communications to that address
go through your DC rather than direct from the client to the website. Depending on what they're doing on the website this may or may not be an issue for you.
2) Since the client is continuing to connect to the DC throughout, if you ever did need the have something on the DC responding to port 80 then you could have issues. That said, according to
https://technet.microsoft.com/en-us/library/cc731068(v=ws.10).aspx the portproxy listenaddress can be a FQDN rather than IP, so that could mitigate any issues there.

Lync 2013 /w Edge not working properly (internal/external same domain name and all "external" users"

Hi,
I've got some issues with a Lync 2013 setup.
The config consists of 2 lync servers. One FE and one Edge. All seems to work except audio in meetings and Sip.
The setup is like this (fake ip's used):
Front End:
Internal IP: 172.16.0.10
External IP: x.x.185.10
All ports open in Cisco ASA
internal AD DNS: dialin/lync/meet/lyncdiscover to Front end internal ip. edge/lsedge/sip points to edge internal ip
EDGE:
Interal IP: 172.16.0.11 (no gateway configured)
External IPS: x.x.185.11, x.x.185.12, x.x.185.13
All external IP's are direct internet facing, no NAT (a firewall is in place).
All external interfaces are using a wildcard certificate.
All server are running in a remote data center, so basically no internal users. We all connect to the external interfaces. The Windows domain name (AD) is the same as our External DNS (companyname.com).
Autodiscover works, we can logon, chat but there is no audio. The audio test failes. Also SIP is not working with a sip trunk.
External DNS: sip/webconf/av are pointing to their external ip's. sipexternal is a cname to sip. lyncdiscover/lync/dialin/meet all point to the Frond end External ip.
_sip._tls/_sipfederationtls.tcp/_xmpp-server.tcp all point to the sip.companyname.com ip.
I just can't figure out what is wrong.

@PSingh123 I'll try the logs in a minute and get back with the results.
@PaulB_NZ Thanks for the input. In my opinion the FE does need an external IP. How else will you be able to connect if you are a remote worker?
The Edge is (asfar as i know) needed for Enterprise voice and Federation with other (external) sip domains. It's not needed for basic (chat/video/whiteboard etc) Lync functionality for both internal and external (remote) users.
The Edge is to communicate with services/users outside the origanisation.
I do still think that the basic topology (FE with internal IP and Nat'ed external ip working with an Edge with internal IP and 1 external IP nat'ed to 3 DMZ ip's) is correct in this case.
I can be wrong and in that case would like to be pointed to the correct configuration.

DNS (internal domain has same name as external website)

Our internal domain name is called "abc.com" and our company website is called "abc.com". I have created an "A" record that points to
www.abc.com so staff can browse the website from within the office. The problem is that if people enter "abc.com" from a web browser with the office it does not resolve in an efficient manner. Can someone please
help?
Interflex

Hi Interflex,
I agree with Ace’s option 2 and 3 just like what I thought.
I still consider the idea which Jorge provided about prevent register DC’s A record . This probably cause some un-expected issues,
because this record is used for DFS and GPOs. So I don’t recommend this method.
Meanwhile , I have thought as same as Ace’s second suggestion, if the environment or policy of your company allow deploy IIS on your
DC server , I thought this could be a possible resolution.
And I have a tips for your reference. If client’s browser is IE, by default, when you type web address in address bar,
and press “ Ctrl + Shift +Enter “,IE will auto add Prefix WWW to the beginning of typed web address. In your case , users just type “abc” in address bar, and press “ Ctrl + Shift +Enter “
You can set this at “Prefix and Suffix option” which located at “Internet Options”/ “General”
Tab / ”language” button.
Thank.
Tiger Li
Hi Tiger,
I've actually found by default, just hitting Ctrl + Enter (without the shift key) puts in the 'www' and 'com.' but it only works for the 'com' TLD' by deffault. I guess you could add 'net' in the General tab, Language, suffix option to use ctrl-shift-enter,
or whatever the actual internal TLD name is.
Cheers!

Mail from my internal domain is not routing e-mail to my subdomain located on googles server

Exchange 2010, Server 2008,
I've migrated my user accounts with the google migration tool to google's mail servers. Now I'm having trouble sending e-mail from my domain account to my sub domain accounts at google mail.
For example
When e-mailing from [email protected] to [email protected] I receive a "Delivery has failed to these recipients or groups: The domain name in the e-mail address is incorrect. Check the address"
However, If I send an e-mail from other domains such as hotmail.com, yahoo.com, gmail.com the e-mails are successfully sent to [email protected] I can also successfully send e-mail from hotmail.com, yahoo.com, gmail.com to [email protected]
The mx records provided by google's mail server are properly set.
I believe the problem lies in my exchange server. It does not recognize the subdomain and seems to be managing the subdomain itself. The bounce back message I receive is:
#554 5.4.4 SMTPSEND.DNS.NonExistentDomain; nonexistent domain ##
Please help

Did you figure this out? I have the same issue. I know it's an old post.

Provision Search in SharePoint Foundation 2013 without Domain Controller / Active Directory - Domain accounts

Hi,
I have successfully setup SharePoint Foundation 2013 as single server farm with SQL Server Standard database in a DMZ environment using local accounts since DMZ doesn't have an Active Directory and hence Domain accounts using powershell as described
in https://theblobfarm.wordpress.com/2012/12/03/installing-sharepoint-2013-without-a-domain-controller
When I run Farm configuration wizard to provision search service application, I get an error:
ERROR: "The service application(s) for the service "Search Service Application" could not be provisioned because of the following error: I/O error occurred."
The log file logged the details of this error as:
ERROR: "Failed to create file share Analytics_e441aa1c-1a8d-4f0a-a079-58b499eb4c50 at D:\SharePoint Search\Office Server\Analytics_e441aa1c-1a8d-4f0a-a079-58b499eb4c50 (System.ArgumentException: The SDDL string contains an invalid sid or a sid
that cannot be translated."
After investigation, I found that potentially the error could be because the timer service is trying to setup a network share for analytics component (as part of provisioning search). It is trying to setup that share with a domain account that happens to
be a local user instead in this case and fails with error “System.ArgumentException: The SDDL string contains an invalid sid or a sid that cannot be translated”.
I got some pointer from the below thread
https://social.technet.microsoft.com/Forums/en-US/c8e93984-f4e5-46da-8e8a-c5c79ea1ff62/error-creating-search-service-application-on-sharepoint-foundation-with-local-account?forum=sharepointadmin
However, the above thread doesn't state that the solution worked.
I have tried creating share manually for Analytics_<Guid> folder but it doesn't work since every time farm configuration wizards is run it creates a new Analytics_<Guid> folder.
Since, I have setup SharePoint Foundation 2013 on a production environment I cannot test and trial various solutions.
Can some please guide me on how to successfully provision search for SharePoint Foundation 2013 setup as a single server farm with SQL Server Standard database in a DMZ environment using local accounts (without Active Directory - domain accounts).
Thanks in advance.
Himanshu

Microsoft documentation doesn't always specifically call out all products (Project Server isn't there, either). But it does apply. You'll need to stand up at least one Domain Controller, or allow port access back to a DC.
Preferably, set up SharePoint on the internal network and use a reverse proxy (which will terminate client connections at the reverse proxy) present in the DMZ.

Internal Domain names

I know what a domain name is for the external web, but what forms of words are acceptable to OS X Server for an intranet? I don't want to have to pay to register a domain name acceptable to the rest of the web, I just want something meaningful for my intranet such as "diary" or "wiki" - or even an IP address alone.
Do they all have to end in .local or will a single word be OK? Should they all start with http://www. or something else? OS X Server help just assumes any website being set up is for world use, and there are no instructions if you just want to set up a private intranet visible only to people on the internal network but invisible to the outside world.
Where can I go for guidance/what formats are acceptable, please?
Many thanks.

Internal domains can be whatever you want. It doesn't have to be a .com, .net or even .local
If you want you can have your own domain .bar then you can have foo.bar as a hostname in that domain.
Since it's only used internally it won't have any impact on anyone outside of your network.
Similarly, if you really wanted to, you could call your own domain 'apple.com' and then have a hostname of basilisk.apple.com pointing to your machine. Of course, this would impact your ability to get to any other .apple.com hostname, so you might not want to do that, but it is possible.
As for the 'single word' question, by definition a hostname is a component of your domain which would mean that 'foo' isn't strictly valid, however, you can configure your machine (System Preferences -> Network -> TCP/IP -> Search Domains) to automatically append specific domain names to any lookup. If you set this to 'bar' then a lookup for 'foo' would automatically look up 'foo.bar' and you'd get the result you're looking for.
Finally, for now, there is no requirement to have 'www' as pointing to your web server. That's just a common convention used around the internet. It's just as valid to have fred.bar as your web server and barney.bar as your mail server if that's what you want.

Mailx command unable to send mail to internal email server

Hi,
I am trying to send mail from my shell program registered as concurrent request in R12 its working fine for external server like (gmail,yahoo,hotmail etc) but when Im trying to send mail to internal mail within organization it fails. It does'nt error out though. Our dba has been working on the same but no luck. Any inputs will be of great help.
echo "Mail"|mailx -s "Test Mail from DEV" "[email protected]" ( fails within internal domain)
echo "Mail"|mailx -s "Test Mail from DEV" "[email protected]" ( successfully sends mail within external domain)
I tried disabling the dns resolution for public sites in the configuration file (/etc/resolve.conf) but no luck. Thanks in advance.
Thanks,
Ahmed

Thanks Koushik for your prompt reply. You mean the configuration file /etc/resolve.conf right? Here you go. If I comment all the below lines the mail does not work even for external sites as well.
-----------------------------------------------------------------------resolve.conf-------------------------------------------------------------------------------------------------
search companymaildomain.com
nameserver aa.aa.aaa.a
nameserver bbb.bb.bb.b
Here first line has the company domain
second and third line is the ip address of primary and secondary dns server
