Hi Andreas,
I'm not 100% sure what you're trying to accomplish.
smtp_server in roundcube is the outgoing server (submission server, i.e. postfix). Mailbox is IMAP (dovecot). You can easily spawn 2 instances of dovecot, one serving aaa.de and one serving bbb.de on different IPs.
How do I do this?
What exactly is the problem with 2 domains on one dovecot? I mean user @aaa.de usually does not have the password for @bbb.de and vise versa.
What is irritating me is that when there are two domains served by dovecot, in the client I can specify server.aaa.de although I have an email-address user@bbb.de and connect as such.
For my understanding it should not be possible to connect to server server.aaa.de with an address line user@bbb.de and dovecot serves the mailbox of that user.
About the sending server in roundcube: I don't think there is a way to have a different submission server for different sender domains in roundcubde. But you could use the postfix configuration to map sender domains to different outgoing connection IPs.
Postfix is not the problem. It's the login into the IMAP-server that is irritating me. Or am I completely wrong?
Regards
Andreas
