Domain name/"primary DNS" name/mail host name/mail server name/mx name

Hi,
I have registered my domain name (N.com) with an external dns server and created an MX record (mail.N.com) for it as well. My server sits behind a router and internet traffic is port(80)-forwarded to my server's fixed internal ip address (I can access my webpages from the internet just fine). When I initially setup the server I was asked to give it a "primary DNS name." I naturally assumed that N.com was supposed to be entered here, but that just caused all kinds of problems (though I still do not understand why). So I reinstalled and currently have server.N.com as the primary DNS name of the server (although it shows up in Server Admin and Workgroup Manager as server.local--why is that?)
I have had no luck getting any email from the internet with the default settings in mail services (domain name of N.com and host name of server.N.com). Having no luck with the defaults, I assumed that maybe I needed to change the host name to "mail.N.com" so that it matched the MX record. I also changed the user preferences in Workgroup Manager to receive mail from mail.N.com--but still no luck. Could someone tell me what I am doing wrong and how come none of the Mail Service literature mentions anything about what a mail "host name" is supposed to be? Is it supposed to be the same as the "Mail Server" name that Workgroup Manager asks each user for? and is it the same as the MX record name?
I am just needing some help to connect all these variously named, but undefined, dots.
Also, how come I can access webmail from the internet using www.N.com/webmail but can't do it from any computers within my physical network (I have to use IPaddress/webmail or server.local/webmail)?
Also, should my user email addresses be [email protected] or [email protected] (which is the current default)?
Thanks in advance and good luck!

I had been told by a friend that ... regular email coming in from the internet would go through port 80
Unfortunately you were misinformed.
My MX record needs the extra subname (such as "mail") in front of the domain name, right?
Not at all. A MX record for 'N.com' is entirely valid (expected, in fact).
An MX record tells remote mail servers where to send mail for any domain/subdomain. If you think about it, let's say you worked for Apple and you wanted people to be able to send email to [email protected], well then you need an MX record for 'apple.com'.
You can see if you dig MX apple.com that they actually have 9 MX records, but the point still stands.
Now, you might also have MX records for subdomains so that you can have [email protected], [email protected], [email protected], etc. Each of these subdomains would need a separate MX record.
So, in general, for any set of email addresses @[anything.]domain.com you have a MX record telling remote mail servers where to send that mail.
Of course the MX record name is mail.N.com, but I think you are implying that the in the Mail settings of Server Admin where it asks for domain name all I need to put there is the N.com, right?
What I mean is that you need to set the domain name to whatever domain name you expect to receive mail at.
If you want users to have email addresses in the form of [email protected], then you enter 'N.com'.
If you want users to have email addresses in the form of [email protected] then you enter 'mail.N.com'.
If you want both forms, enter one in the main domain and add the other(s) in the Advanced -> Hosting -> Local Host Aliases section.
Is there anything in the Mail settings that needs to have the full MX record name (mail.N.com)?
Yes. Either the 'domain name' or the 'Local Host Aliases' needs to contain the same thing as your MX record. That's because the MX record tells remote servers to send mail to this machine, but the machine won't accept the mail unless it is configured to do so.
What is the "host name" supposed to be?
This should be the name that remote servers see when this machine tries to send outgoing mail.
Ideally this should match the reverse DNS of your IP address, that way when it connects to a remote server it says "Hi, I'm $hostname" and the remote server can lookup the machine's IP address and see the same result. This will reduce the problem of remote servers thinking you're sending them spam.
If you only have a single IP address then this probably needs to be something like 'N.com'. If you don't have control over your reverse DNS then you're going to run into a problem.
Also in the user accounts (in Workgroup Manager) what should the "mail server name" be? Is it the host name or the domain name?
Off hand, I don't know.
Also, why are all the default user email addresses [email protected] (the name I gave the server at setup)? Why doesn't the user accounts create [email protected] as the default address?
Presumably because the mail server says it is 'server.N.com' and therefore any accounts on that machine would be [email protected]. Changing the domain name (as above) should fix that.

Unable to send mail to Lotus Mail

Hi,
I tried to send mails from SAP to Lotus Mail and failed. In SCOT, the SAPCONNECT parameters for the node I am using are:
Node: SMTP
Max Waiting TIme: 30 min
Node In Use: Checked
Mail Host: w2kdev01
Mail Port: 25.
Internet: Checked
During troubleshooting, I tried to telnet in the SAP server and received the following:
C:\Documents and Settings\devadm>telnet w2kdev01 25
Connecting To w2kdev01...Could not open connection to the host, on port 25: Conn
ect failed
Telnet-ing to server IP address doesn't work too. Telnet-ing to localhost 25 works though.
Any advice on how I should proceed from here? Points will be rewarded for useful replies. Thanks!

Hello,
Is w2kdev01 you Lotus Mail server or your SAP system ?
You should check from the SAP host if it's possible to telnet on port 25 of the Lotus Mail server.

How to set same domain name for Azure Storage and Hosted Service

I have a web application running on azure and using azure storage with blob. My application allows to edit html files that are in the azure storage to save with another name and publish them later. I am using javascript to edit the html content that
I display in an Iframe but as the domain of my web application and the html that I try to edit are not the same, I got and this error "Unsafe JavaScript
attempt to access frame with URL "URL1" from frame with URL "URL2". Domains, protocols and ports must match".
I have been doing some research about it and the only way to make it work is to have the web application and the html that I want to access using javascript under the same domain.
So my question is: is it possible to have the same domain name in azure for the hosted service and the storage.
Like this:
hosted service: example.com
storage: example.com
By the way I already customize the domain names so they looks like this:
hosted service <mydomainname>.com
storage <blob.mydomainname>.com
Actually I have my application running in another hosting and I have no problem there since I have a folder where I am storing the files that I am editing so they are in the same domain as the application. I have been thinking in to do the same with Azure,
at least to have a folder where I can store the html file meanwhile I am editing it but I am not sure how much space I have in the hosted service to store temporary files.
let me know if you have a good tip or idea about how to solve this issue.

Hi Rodrigo,
Though both Azure Blob and Azure applications support custom domain, one domain could have only one DNS record (in this case is CNAME record) at one time. For Steve's case, he has 3 domains, blog.smarx.com, files.blog.smarx.com and cdn.blog.smarx.com.
> I would like to find a way to storage my html page that I need to edit under the same domain.
For this case, a workaround will be adding a http handler in your Azure application to serve file requests. That means we do not use the actual blob url to access blob content but send the request to a http handler then the http handler gets the content
from blob storage and returns it.
Please check
Accessing blobs in private container without Shared Access Secret key for a code sample.

Exchange 2010 Domain Name change in a multitenant (hosted) environment

Is there a way to change a domain name from one of our domains?
We have exchange 2010 SP1 in hosted mode so we have several domains we deliver to our customers.
However, now 1 of our customers would like to change their domain name.
For example abc.com should become 123.com
To make it even a litle bit more complicated, in the first instance they want to add the 123.com domain so they receive emails on both domains. After a month they want to delete the old domain ( abc.com ) and keep on receiving emails on the new domain
( 123.com ).
Please keep in mind that the other domain that we also provide must not be affected.
Any help would be grate as I am stuck on this one.
I simply don't know the correct powershell commands.

Hi Peter,
I read the email and as I was writing a reply I thought by myself, why not share it with the rest.
I am sure other people need this to so I copy paste it in here :-):
===================================
Hi Peter,
If this helps you out, the only thing I want back is for you to help 3 others and share this message so they help out other people aswell. :-D peace
Unfortunately there is no way according to microsoft ( as far as I am aware ) to make a domain change in the hosted edition and for this reason I had to figure it all out myself.
I am no scripter so I didn't build a tool for it, sorry.
I will send you all the information you need.
1- add the accepted domain: New-AcceptedDomain -Name NameOfOrg -Organization ForWhichDomainWillThisBeTheAcceptedDomain -DomainName NewDomain.Eu -DomainType Authoritative
2- to create an alias ( tenant admin )
Import-CSV name-of-textfile.txt | foreach-object {Set-Mailbox $_.alias -EmailAddresses @{add=$_.smtp1}}
The text file has to be in the following format:
alias,smtp1
firstalias,newemailaddress
secondalias,newemailaddress
etc.
3- Make the new alias the primarysmtpaddress ( main exchange admin ):
Import-CSV name-of-textfile.txt | foreach-object {Set-Mailbox $_.alias -primarysmtpaddress $_.smtp1 -emailaddresspolicyenabled $false}
The txt file should be in the following format:
alias,smtp1
domain\alias1,newemailaddress
domain\alias2,newemailaddress
etc.
4- Rename the alias ( tenant admin ):
Import-CSV name-of-textfile.txt | foreach-object {Set-Mailbox $_.alias -alias $_.smtp1}
The txt file should be in the following format:
alias,smtp1
alias1,newalias1
alias2,newalias2
etc.
5- Change UserPrincipalName (main exchange admin ). This is the username to sign in to OWA
Import-CSV name-of-textfile.txt | foreach-object {Set-Mailbox $_.alias -userprincipalname $_.smtp1}
The txt file should be in the following format:
alias,smtp1
domain\alias1,newemailaddress
domain\alias2,newemailaddress
etc.
6- Change displayname (tenant admin ):
Import-CSV name-of-textfile.txt | foreach-object {Set-Mailbox $_.alias -displayname $_.smtp1}
The txt file should be in the following format:
alias,smtp1
alias1,displayname
After a while you might to remove the previous email address ( i waited for this for 3 months! 1 month is way to short for people to communicate it, trust me.. ):
7- Import-CSV name-of-textfile.txt | foreach-object {Set-Mailbox $_.alias -EmailAddresses @{remove=$_.smtp1}}
The txt file should be in the following format:
alias,smtp1
alias1,OldEmailAddress1
alias2,OldEmailAddress2

Primary DNS Name: during Standard setup

Hi I hope you can help, I am installing Mac OS X Server via the Standard setup and all is going fine until I get to the point where it asks me to give the computer a name and underneath it displays the Primary DNS Name: currently it displays Bunnymen.config (Bunnymen being the name of my homenetwork device on my router), I believe that it should display standard.bunnymen.com (I own the name bunnymen.com along with a static ip address that the web address points to).
Do I need to set something up on my router first to show the correct address etc.
Any help would be great.
Thanks

OSX Server will get it's computer name from the reverse DNS lookup against the IP address. There is no forward address for either bunnymen.com or standard.bunnymen.com. Before proceeding, I would suggest that you fix the DNS names or you will start to have problems. You needs both forward and reverse addresses set up.

"404: No group with that name (wikigroupname) hosted on this server"

I am running 10.6.8 as our wiki server. After rebooting the server, one of the wiki group seems to be not accessible. When try to access the web page it gives error "404: No group with that name (wikigroupname) hosted on this server", though it still exists in /Library/Collaboration/Groups/wikigroupname
Do you know how to make it viewable again? I tried to create a new wiki "test" and then rsync /Library/Collaboration/Groups/wikigroupname to /Library/Collaboration/Groups/test, yet still can not see the old wiki group.
Thank you in advance for you help.

In all due respect Antonio, I believe that Francesc43 is fighting a flakey system. The 404 No Group is a problem that is confirmed by Apple according to others and very prevalent. At this point the only remediation appears to be a complete server rebuild and to avoid going beyond the "default" configuration for web domains.
I have personally used only the 'any domain' default config, had the server working fairly well. I then added a FQDN and the server started giving 404s for all groups which previously worked and have data in the wiki. At the same time the simple web sites worked with and without the FQDN as expected. Then removing (not disabling) the default web domain config relieved the wiki 404s. Adding a new default domain config back in (via just hitting the "+" and "Save") recreated the 404's for the previously working wikis with no change to the groups. Removing the system created default domain config it alleviated the 404s.
Adding a system generated default and a 3rd FQDN re-created the issue and then afterwords, removing all but the FQDN that worked could not alleviate the 404s. Regardless of the permutation of turning things on and off, deleting groups, removing webservices settings, putting them back in, restarting the server.. nothing. 404-DOA
While the mystery seems to be related to a very fragile relationship with DNS on the server, the solution is again to erase the disk and start over. Wikis in 10.5 thus far are neither a robust nor a stable solution from 10.5 thru 10.5.5 in my experience.

Do I need a domain name in order to connect to my Mini Server 10.8.2 from outside my network?

I am working on setting up my mac mini server. Aside from in home file sharing I want ot be able to connect to some files remotely and even upload files, say pictures from my camera, to my server from outside my network. I am only looking to have maybe 2 users that have access. Should I get a domain name from a place like GoDaddy? in order to set up server to use domain in initial setup? I have 2 Drobos connected with my music, videos and pictures and I wat to access them from an Android, Windows and iPod device when away from home. Any how-tos out there or good step by step guides?
Thanks for any information.

A normal address like www.domain.com is intended to work with static IP addresses, DynDNS is a service specifically intended for dynamic addresses and it will therefore automatically update the address e.g. name.dyndns.org to match the dynamic IP address each time it changes.
Some home broadband routers have built-in support to act as a DynDNS client but if yours does not then you can run the DynDNS software on your Mac server. This will then tell the DynDNS servers what your current dynamic IP address is so they can map it to your host name.
The result will be that your users can use a name like yourname.dyndns.org to access your server and not have to worry about the fact your IP address may change.
You would still need to run a VPN server to allow your remote users to connect to your network but OS X Server can do this. You could also run a website but depending on your needs that might be better done by using a web hosting service.

Finding LDAP server names by DNS lookup.

Hi,
I'm very new with JNDI and DNS
We are hardcoding the ldap server name in our configuration to connect to the Active directory, but the requirement is to know the ldap server name dynmaically by querying the DNS server.
The input given to us are below.
Dns domain : indbank.is.
SRV RRecord : ldap.tcp.
Query dns : ldap.tcp.indbank.is.
The domain controller should be found by a DNS lookup for the domain, then a DNS for Domain controllers that advertise the service, then try to see if the domain controllers areanswering, and if so choose the one with the fastest answer time (to avoid choosing a domain controller over WAN).
Kindly help me.I am beginner and some code sample and tip will be welcome. :)

The code runs fine and I get the output as follows
0 100 389 ib500ad1.indbank.in
0 100 389 ib500ad2.indbank.in
I have following questions
1) Do these servers which are returned are the domain controllers or the ldap servers.?(or both domaincontrollers and ldap server are same)
2) how to extract the server name alone from this string.
3) If these two server names are domain controllers then how can I query for a DNS for Domain controllers that advertise the service, then try to see if the domain controllers are answering, and if so choose the one with the fastest answer time (to avoid choosing a domain controller over WAN).

Wiki - No group with that name hosted on this server?

I tried to create a wiki for a group of users on my server. Unfortunatly I couldn't get it to work through the external website. Everytime I returns the error "404: No group with that name (team) hosted on this server". But when I went to the internal adres of the server "10.0.3.1" the wiki worked fine, although I selected the FQDN at "Enable the following services for this group on".
I searched the forums but no solution helpt. I checked the MAC address, restarted teams, restarted webservices, rebooted the server. Because nothing helpt I recreated my opendirectory database. Filled it with all users again but it still doesn't work. However, when I go to server admin and then to "Sites" all my sites are gone, although they do work, I can't edit any of the settings. In Workgroup Manager at "Enable the following services for this group on" I can only select "NONE".
It looks like Server Admin and Workgroup Manager are out of Sync and Server Admin also lost his previous settings. I tried to import an backup of the webservices, then the new sites appear for a few seconds and then disappear again.
Any advise?

It sounds like you have a DNS problem. You have one hostname/IP for the 'world' and another hostname/IP for your internal network. You need to reconcile that before you will get the wiki to work. Start with this in Terminal.app:
sudo changeip -checkhostname
Then do:
sudo hostname

DHCP Name Protection & DNS Records

How correlates DHCP Name protection & DNS records for domain PC? We found a lot of old records from PC's in DNS, and I'm just wondering, does DNS (or DHCP) removes records about PC, which were removed from AD (not gracefully, just deleted computer
account)?

Hi,
If you want the DHCP server to register the DNS records for the DHCP clients, you need to configure the DNS configuration and options settings on DHCP server. In addition, it seems that Windows DHCP clients cannot update their records with the DNS server themselves,
but DHCP server can be configured to perform updates for both Windows DHCP clients and non-Windows DHCP clients. The links below may be helpful to you:

In Mail, the "From" line shows the wrong name associated with the email id. How do I update it?

In Mail, the "From" line shows the wrong name associated with my email ID. I've looked over preferences and account information but have not found where I can update it.

There isn't an email address associated with the contact name who appears as the "from" in Mail. It used to be a shared email address and I already had updated the contact to list only the phone number in case that was causing the problem.

I want to sync my I phone user name (my current e-mail address) with my iPad, PC user name (old e-mail address.) If I delete that current address in the iPhone, won't I also be deleting it in my other devices? They are synced. I don't want to lose it

I just want to get it out of the way on my iphone so it doesn't confuse the transfer of ID names and then I want it back again.. I tried deleting the cloud account, being told the current e-mails would be spared. But all it did was pop up a prompt asking me for the password to my still current email ID. So I assume now that I have to go to mail and get rid of the e-mail account. But I'm scared I'll lose everything in my other devices too.

You can change the email address you use as your apple ID. this doesn't mean you have to delete the old email address as email.
When you delete an email from your device, it is only removed from the device, it does not delete your emails or the email account.

IN IPAD AIR How can i send an e-mail to several mail adress typing a group name, similar procedure used un gmail wich is very frendly

Before all these updates, one used to be able to create a Group (such as Buddy List), then send emails by clicking on that Group Name. Has not worked for a long time now, though. I wish they would bring it back.
