Securely Configure HT to Accept E-mails from non-Exchange SMTP Gateway

Hi
We have setup a new Exchange 2010 environment. We are not using Edge Transport servers as SMTP gateway, rather using a hosting service named ProopPoint. The ProofPoint gateway accepts e-mail for our SMTP domain
and after performing anti-spam etc. functions, is supposed to send e-mail to internal Hub Transport servers in our domain. We need to allow the ProofPoint servers to send e-mail to our HT servers (HT servers should accept connections from ProofPoint servers).
I know that I can go to the “Default <Sever_Name>” receive connector on each HT and on the
Permissions Group tab check the “Anonymous Users” to allow ProofPoint servers to be able to submit e-mails to HTs but that won’t be a good idea as (I think) this would make my HT as “OPEN RELAY” (pls. correct me if I’m wrong)
as that Default connector is configured by default to listen from any IP addresses. So want to know:
If this is the only way I could achieve this?
If I configure a separate “Receive Connector” on my HT servers and configure only IP Addresses of the ProofPoint to be able to submit e-mails to HT – Will this work?
Also, is there a way I can restrict user(s) in Exchange 2010 to send only 30 messages per minute?
Any ideas and/or supported documents would be highly appreciated….

Hi
When I create a new Receive connector, I have to specify the type "Intended Use" of the connector in terms of Internal/Custom/Internet etc.. What option do I need to select here?
If I select Internet, I do not get any window to put Remote IP Address and if I just go with default configuration in the connector creation, it gives me the following error:
Failed
Error:
The values that you specified for the Bindings and RemoteIPRanges parameters conflict with the settings on Receive connector "<Server_Name)\Default". A Receive connector must have a unique combination of a local IP address, port bindings, and remote IP address
ranges. Change at least one of these values.

Also, what options do I need to select on the "Authentication" and "Permissions" tabs of the connector?

Need to send mail from Microsoft Exchange 2007 account(different from Gmail) on behalf of another Gmail ID. How to configure that ?

I have a Gmail ID (e.g [email protected])
I have a Exchange ID (e.g [email protected])
I need to configure exchange account (2007) such that I can send a mail from my Exchange account but at the receiver end it looks like it was sent from ([email protected]).
Both the accounts are my accounts.
I need this because I do not have access to my Gmail account from place where I access the internet and I need to send the mails from my Gmail account only.

So you want to spoof your e-mail address.
You can make your Exchange server send as any address you want. Just create a different mailbox with that address as the primary (reply) address. It has to be a different account.
However, be aware that many systems to which you send such mail to will bounce it as suspected spam because they'll detect that your server is sending mail from Gmail but your server is not Gmail.

Dpm 2012 email notification using a non-exchange smtp mail server

Has anyone successfully been able to configure DPM 2012 to send email notifications to a standard SMTP mail server (NON-EXCHANGE)?

Hi Happy,
I try with IIS6 SMTP server with Anonymous Access.
From DPM side, settings for "Authentificated SMTP Server: Username/password" :
1- Leave blank =>ID 2013 : logon failure : unknow user name or bad password.
2- DPMServerName\UserAccount => Works :)
Network trace with Wireshark :
1- Nothing => Most likely blocked by DPM console : Authentificated SMTP Server must be fill.
2- See full SMTP connection, mail send.
Could you do network trace to see what's happen ?

Unity: Voice-mail for non-Exchange subscribers

Hi everyone!
I have this issue: customer wants to enable voice-mail for non-Exchange users, I've created them as Internet subscribers for using with auto attendant, but I can't enable voice-mail for these extensions, basically the customer does not want for this users to receive the messages in their mail just only check it on IP phones. Is there a possible way???

Configure postfix to accept inbound mail only from Google

I like to host my own email on a Mac Mini running OS X Server. I’ve also looked for solutions that allow filtering out SPAM before the mail gets sent to my server. For many years I used Postini’s spam filtering service to clean incoming email before Postini forwarded the mail on to my server. I now use Google mail, part of Google Apps service to remove spam and to archive all the mail.
The approach of letting Google clean emal before sending the mail on to my OS X Server uses two domains, one a “public” domain for incoming email and another a “private” domain used only for forwarding the filtered email to OS X server.
All went well with the defult Postfix configuration that came with OS X Server for a few months, then SPAM started creeping into my “private” domain as various spammers discovered my private email address and started sending mail directly to the Mac Mini, bypassing Google.
Whenever I had spare time I would search the web looking for how to configure Postfix on OS X server so that email from Google and my other machines would be accepted and all other email would be blocked. There were lots of write-ups on how to relay outgoing email to Google, but I couldn’t find straightforward configuration instructions for configuring Postfix to only allow incoming email forwarded by Google or coming from my machines and block all other sources.
With a Google apps account you get telephone support so I gave Google a call and within a few rings got a very pleasant guy who listened to what I wanted to do and didn’t have the configuration setup, but did offer to send me a document showing the blocks of IP addresses used by Google for sending email.
I’ve posted several requests for help doing this type of configuration and never received responses that made sense. So in the interest of helping anyone else that wants to configure Postfix to accept connections from a set of specific IP addresses and refuse connections from all other connections for inbound email, here is what will get you going:
Use your favorite text editor to edit the Postfix configuration file (I use BBEDIT) but use whatever you like.
On the OS X Server open this file:
/Library/Server/Mail/Config/postfix/main.cf
Immediately do a “save as…” to make a backup copy with a different name, such as …mail.df.back1 in the same directory so you can revert to the backup if necessary.
substitute your domain names in the following commands:
public.com   - change to your publicly advertised routable domain
hidden.com - change to your OS X Server routable domain
lan.com - change to your OS X Server lan domain, should be registered to make things clean and shouldn’t be .local
10.6.18.0/24 - change to your LAN subnet
host - change to your host name
Your Postfix configuration file should contain these commands (and probably more). Each situation varies so do what you have to for your situation….
Have Postfix add your public domain name in the email header
myorigin = public.com
mydomain_fallback = localhost
message_size_limit = 41943040
biff = no
aaa.bbb.ccc.ddn - Your publicly routable IP addresses provided by your ISP
Let Postfix know your LAN network, the routable addresses you have from your ISP, and the Google networks where the Google email servers live. Get the latest list of Google networks hosting email at this address: https://support.google.com/a/answer/3070269
mynetworks =

Any suggestions to make this better or more efficient welcomed!

After a few telnet tests I can answer my own question: It makes an open relay server to spammers! But to solve the former issue with the connection refuse, I had to switch to virtual hosting in the advanced tab of the mail service and add my own domains.

10.5 - 10.6.2: Postfix not accepting e-mails from certain hosts

Hi
Two days ago we migrated our server from 10.5 Server to a new Mac mini server running 10.6.2 server.
We are now facing the problem that postfix refuses to accept incoming e-mails from most hosts. Some hosts seem to be able to get through, but so far we haven't be able to identify a pattern.
The transfers just times out with various error messages. Below is one of the shorter transscripts. Any ideas where to start looking?

Hi again,
I was able to further narrow down the problem. The remote server is sending a complete message but postfix on our mac doesn't recognize the end of message token, thus timing out the connection after 5 minutes.
Any ideas? Is this a postfix issue? If so, what can we do about it.

Sending mail from non-BT accounts

I have email accounts with Apple (mobileMe), my own domain (hosted by Verio) and another of my own domains (hosted by Network Solutions) - as well as the BTinternet.com email account.
Until today, all four accounts were set up on my email client (Apple Mail) to use their own respective SMTP servers for outgoing mail, and all four have worked fine in this way for literally years.
This morning, I started getting error messages trying to send mail from the domain hosted by Verio ("cannot send message using the server [my own domain's SMTP server]").
In the end, I followed the steps outlined in a thread on this forum to "add" the account to BTYahoo, verify it, and change the email client settings to use BT's SMTP server. So now it works fine.
What I don't get is why I had to change this one account, when the other non-BT accounts (Apple and NS SMTP servers) continue to work fine as they are (ie using their own server details for outgoing mail).
Anyone know the answer? Obviously it works, so there's no problem (apart from wasting 2 hours this morning trying to figure out what the **bleep** had gone wrong), just curious as to BT's logic here.
Solved!

Hi Gregch.
To be honest, the problem seems to be at the destination smtp service end and nothing to do with BT. You've not really supplied any details of the error message - is there anything else in the received message ?
You've assumed that it's a BT fault, rather than perhaps investigating the possible error at Verio. As the other accounts work as exists, it really does point at Verio (or indeed something local, perhaps a security package interferring etc).

No content in rich text mails from MS Exchange with attachments

After upgrading to Yosemite I cannot see any content in mails received from MS Exchange in rich text format when they have an attachment. In Mavericks I can see the content (text) of the mail and the attachments in form of a file called winmail.dat. But in Yosemite I only see the header and the content pane shows a loading animation. When I look in the Library folder I can see the mail in my inbox folder. It has multiple parts, one .partial.emlx and one or more with .emlxpart. When I boot my backed up Mavericks installation, everything is fine. So I think it's a problem with mail.
Any help on this?
Best regards,

Can't send messages from Mail from Comcast account - "SMTP not responding"

Using Mail and a Comcast account, I can receive but not send. The error message on trying to configure the outgoing mail server says the SMTP server isn't responding. If I click continue to set up the account in Mail, then go to Mail Preferences and tweak the ports between 587 and 25, triple check the username and password for the outgoing server, etc. -- still no dice.
I wonder if this might be the problem: Is it possible to configure Mail when you're not using a Comcast installed modem? I'm trying to get my Dad's account up and running on my old Mac with my airport extreme to earthlink modem connection (which works fine for Earthlink and .Mac e-mail accounts.) Apple support and Comcast tech support are both stumped on this one, referring me back and forth to each other. HELP!
Thanks.

If I'm understanding this, you are trying to send messages with a Comcast account and SMTP server while connected to the internet with Earthlink?
If so, this is the cause of the problem. All ISPs now have restrictions on using an SMTP server that is outside of their network or not provided by the ISP used for connecting to the internet.
If you are connected to the internet with Earthlink at this house in California, contacting Comcast about a sending problem with their account and SMTP server when connected to the internet via Earthlink is a waste of time. You need to be contacting Earthlink if you are using Earthlink for your internet connection.
Do you also have an email account with Earthlink? If so, you can select/use Earthlink's authenticated SMTP server to send messages with your Comcast email account while connected to the internet with Earthlink or call Earthlink technical support regarding their required settings for an SMTP server that is outside of their network or not provided by Earthlink.

Mail app on Tiger and Leopard no longer bring in mail from non-apple servers

My husband's computers use Tiger and Leopard (10.5.8) to access his email on the Mail program. His mail is from Comcast and uses the Comcast server, not apple or iCloud. His mail suddenly stopped working a couple of days ago.....as it did on one of my machines that still uses Tiger. He had not done any updates that could have broken the software. He does not have iCloud except on his phone and he doesn't even have a .mac address. There is no reason for the comcast server to not be able to be accessed by Mail app.
He did finally update everything that needed it and it still does not work. Why would Apple's change over to iCloud break email access from other servers and how can we fix it. He really doesn't want to do his mail on Comcast's web site as it's slow and awkward.
Thanks for any help you all can offer.
Paula

Thank you for answering.
I know it shouldn't have been able to stop those accounts from working on the Mail app but it did.Out of 4 machines, 3 stopped working at the same time. The 4th is on Snow Leopard and continues to get my Comcast mail. But the one Tiger machine and 2 Leopard machines no longer access any mail from any server. Shouldn't be possible, but it happened.
I don't want to delete accounts because I don't want to lose the old email in the different folders on there and the software is acting so bizarrely, I know the mail would be lost.
I checked all the settings and compared them to the one on Snow Leopard that still works. The settings are all the same. The only difference is the OS.
And to make things more frustrating, I found that several entries in my Contacts book were either deleted or scrambled with phone numbers for person A in the entry for say, person C. I mean it's a real mess and this all happened after I got a notice from Apple that they were shutting down all their mobile me stuff and sending everything to iCloud. Syncing is obviously a mess now and I don't even want my stuff sync'd there. My husband has never even signed up for iCloud but since he has an iTunes account, thus an Apple acct, they appear to have automatically put him on iCloud too. And....mail quit working unless he gets it on his iPad or iPhone.
We're fed up with Apple's insistence on total control of it's customers' previously working equipment. We have no desire to upgrade to Lion or it's next iteration. We have been happy with what we have and asked only that it continue to just WORK.
It's become a rotten Apple in the past few years. We've been with them a long time but we're watching other companies closely for something that will do what we need without the draconian control.
I have a feeling the only way to "fix" Mail.app is to upgrade to Lion and we won't be doing that.
Thanks again.

Will the email client on my MacBook Pro remove mail from my Exchange 2003 in order to receive it?

I just received my new MacBook Pro yesterday and I have an Exchange 2003 server that I would like to work with the email client. now I know some email clients in certain modes will download the mail from the mail server removing it from there at the same time. My question is will the email client remove the mail from the server in order to receive it? I want the mail to remain in the mailbox so I will still have it available at my office later. I am honestly not certain what version of OS X it is, and I don't have it handy, but I just bought it last week. Thanks!

Try trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder. (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
What's the plist file?
For new users: Every application on your Mac has an accompanying plist file. It records certain User choices. For instance, in your favourite Word Processor it remembers your choice of Default Font, on your Web Browser is remembers things like your choice of Home Page. It even recalls what windows you had open last if your app allows you to pick up from where you left off last. The iPhoto plist file remembers things like the location of the Library, your choice of background colour, whether you are running a Referenced or Managed Library, what preferences you have for autosplitting events and so on. Trashing the plist file forces the app to generate a new one on the next launch, and this restores things to the Factory Defaults. Hence, if you've changed any of these things you'll need to reset them. If you haven't, then no bother. Trashing the plist file is Mac troubleshooting 101.
If that fails:
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .
