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. 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. 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. Does this help? If not, please tell us more about what you're trying to do. regards Marco On 27.09.2015 19:53, Andreas Meyer wrote: > Hello! > > I asked myself wether it is possible to distinguish between > different doamins in dovecot so that a user only sees his > mailbox when he is connecting with us...@aaa.de specifying > the server with mail.aaa.de for example. > > So the server does not handout the mailbox for us...@bbb.de > when the client connects to mail.aaa.de as us...@bbb.de > > I have this problem with roundcube.
