Ubuntu Servers :: Postfix Relay - Exchange Sends The Mail Instead Giving Recipient Mail A Valid Reverse DNS Lookup
Jan 12, 2011The scenario: We have an external server that runs HTTP/DB servers for out shop system. Then, there's our local, in-house infrastructure that runs a.. yeah... Exchange 2010. The shop system on the external server needs to send mails to customers (order confirmations, invoices, etc.). seing as sending them directly through the local MTA (Postfix) would cause mail delivery problems because of reverse DNS issues, i've set the Postfix MTA to act as a satellite to our in-house Exchange Server, so the Exchange sends the mail instead, giving recipient mail servers a valid reverse DNS lookup.
Now, mails sent by the (proprietary, uneditable) shop system are relayed correctly and sent to the target e-mail address. My problem is: Mails not sent by the shop system, but by our own PHP scripts which run on that same external servers, are NOT relayed properly. So the Exchange is fine with the mails sent by the shop system, but not the mails sent by our scripts. This is what i get in the mail.log: The successfully relayed mail sent by the shop system:

View 8 Replies View RelatedServer :: Internal Mail Relay To Exchange Setup
Jan 25, 2010I have ticket tracking software that mails ticket to groups. Right now the software is on an exchange server. After moving it to a dedicated linux server (debian lenny) I cant get it to email any of the internal domain addresses. I have tried to setup sendmail to relay it to the exchange server. Logs indicate that it was sent by the ticket tracking software but the message never hits the mailbox. It also wont get to any other mail address. Is there a better way to do this? The crm software will utilize either a smtp server or any mail server on the localhost. The problem is that with the dedicated server on the same network as the exchange server, it fails to send the mail even if I assign an external smtp server. But if the dedicated server is on a different network then it works using any smtp server in its configuration. I need something that can "pass the email" to the exchange server. Or just be able to send the mail to internal email account and still be on the same network.

Jan 31, 2010I've got a server set up with Debian. The problem is that my ISP doesn't allow usage of port 25 (as I understand a lot of ISP's don't).I have PHP scripts hat use the mail() function to send e-mails through the Sendmail application.So, my question is: How can I relay messages sent to sendmail to an external SMTP server (like Google Mail, for example)? Would this be easier to do in the PHP configuration, or on the Sendmail side of things?I've used PEAR extensions in PHP to achieve this before, but scripts downloaded from the Internet generally just use the basic mail() function, and it would be a real pain to modify them all.

Jan 29, 2010I have postfix setup right now and it's relying mail to our Exchange server fine. What i would like to do though is have postfix save the email that gets passed through so that if a manager deletes an email, it's easy to look through by date and find the email he's looking for. Well, I'm thinking it would be a lot easier then having to need to pull out the backup tape and try to recover one email. Does anyone know whether I would be able to accomplish this?
View 3 Replies View RelatedServer :: Get Postfix To Deliver Valid Emails To Maildir And Relay Remaining?
Jan 20, 2010I got a weird postfix setup question? This is a separate server to the one I posted about earlier today.
I need to setup a postfix server which will accept emails for local know address (full addresses) and deliver them straight to the users maildir.
Any unknown addresses (however for the same domain), needs to be relayed to another server.
This is a bit of a special setup as there is no fixed Internet connection to the server. So the plan is that local email get delivered straight away whilst emails to the same @domain, but that doesn't exist in the user tables get put in the hold queue and is later relayed to server number 2 when a connection is available.
I am using mysql to retrieve all my settings into postfix.
Server :: Setting Up Postfix As Outgoign Mail Relay For Several Domains / Hosts
Oct 6, 2009I would like to setup postfix to act as a relay for the outgoing mails of a couple of servers each serving it's own domain.The mails we are talking about are standard administrative emails like user registration, password reset request. The volume of those mails will naturally grow as the site grows. Which for me poses the problem that depending on the growth of the site you will sooner or later hit the quotas imposed by (my otherwise preferred) providers like GMail or smtp.com.
So what I need is a mail relay that will only accept mails from authenticated clients from hosts in its access list and relay their mail without restrictions. Is that possible with postfix? What has to be changed in the config and what are the pitfalls?
