Configure Zimbra to Accept Mail from a postfix bastion host

[lucac81]

Hello
I've downloaded ZCS 6 to test exchange like functionalities, so I want it to stay alongside my main system and route only some accounts on it.
My system is built using postfixadmin(So sql auth, postfix and dovecot) and uses a separate postfix server to clean from crap (clamav+amavis)

The bastion host checks mails and redirects them to the other mailserver using a transport map.
since I want to redirect only some accounts to zimbra I've added them to the transportmap
(like this test@domain.com smtp:zimbrahost.lan )
It seems to work on my side, but zimbra won't accept mails coming from that server.
How can I configure it to accept mail from my bastion host?

Your descriptuion doesn't actually tell us what the problem is, why don't you have a look in the log files to see what the exact problem is.

Wild guess: Zimbra comes out of the box configured with good spam filtering, so if your bastion host does not "present" itself to Zimbra as a properly configured public mail server (think DNS), Zimbra may not accept emails from it.

Please look in /var/log/zimbra.log and post some specific reject messages.

A few other things to check:

Did you configure the bastion host as a relay MTA in Zimbra? Is the bastion host on a subnet not listed in Trusted MTA Networks?

Again, in the absence of logs... :-)

Hope that helps,
