How i can set automatic select relayhost by sender identity in Roundcube? I have this in iredmail - one local account, fetchmail from 5 mailboxes and i can send from this local mailbox as any from identity list. Work well, enough is add table in mysql for postfix, but i cannot find similiar option in mailcow. Only one relayhost for account is possible. How i can change this to set automatic select relayhost by sender address?
