In this document, it is explained how to set up Global relay host or Sender dependent relay host:
http://www.iredmail.org/docs/relayhost.html
I want to set up per-user sender dependent relay host, so that mails sent from newsletter@mydomain.tld (and only from this mailbox) are sent over another SMTP server (as my provider doesn't want newsletters to be sent over their server).
Now, it is explained on this page how to set it up via MySQL.
Where to put username and password for the relay, though?
Also in /etc/postfix/sasl_password as for the global relay host?
Is it possible to establish a encrypted connection to the SMTP relay if it supports it? If so, how?
