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?
