Server :: Send Mail From Exchange Server?

Apr 5, 2010

I have set up ubuntu server V9 with squid, dansguardian and clam. I have fetchmail wroking to bring in mail from our externally hosted website and delivering it to users mailboxes in exchange server. That was easy following guides on the internet. However my brain is failing me now. How do I reverse the process and send mail to the outside world. I need to be able to do this without authentication. At the moment i am using a windows environment with exchangepop3 which uses smarthost to connect to the ISP smtp server. Please help or point to a simple guide. If i cannot solve this soon i will have to revert to microsoft solution for the proxy server.

CentOS 5 Server :: Postfix Save Mail Before Relying It To Exchange?

Jan 29, 2010

I 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?

I have a server with a domain running and im trying to resolve the mail server but i can't see where to start. I use OpenSuse 11.2.

I configured the dns. I do a dig.mydomain.tld MX and i get the following:

mail.mydomain.tld 3600INAmyNumericalIp

Ubuntu Servers :: Postfix Relay - Exchange Sends The Mail Instead Giving Recipient Mail A Valid Reverse DNS Lookup

Jan 12, 2011

The 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:

I have a Nagios box set up on the corporate LAN. I'm trying to get it to send emails to both internal Exchange addresses as well as doing a direct delivery to internet domains.

I have looked at a few logs and it appears that Postfix is not doing proper DNS lookups on the internal servers. It keeps trying to connect to the domain controllers. I have an MX record specified.
