Exchange/postfix working together
Hi!

Is there anybody having experience using exchange and postfix?

Due to chost reason I want to use postfix as external MTA.
In our DMZ we have an Exchange-Server with OWA.
Our users want to have Webaccess for External use.
If there comes the question why I don't use imp/horde or something like that - I gave it a try but it wasn't accepted.

My config is, that postfix gets mail and redirects it to amavis and then transmitts virus free mails to the exchange-server via the .forward.
This way is secure and is scanned.
The users then may send mails to external servers with the exchange-server and the recipient may return mail to this account.

Is it possible to rewrite headers of the exchange-server's outgoing mails, that all mails are from the linux-server?
Or is there any other way?
This would minimize my problem.

Philippe
