Hi, I'm not sure if i got myself confused but here is what I'd like/have to achieve:
If an internal user is sending an email and postfix receives a bounce, the Mailer-daemon should have the hostname as domain part. I know that I can use $myhostname to set $myorigin for that. But I'm not sure if that affects anything that postfix may send to external recipients. (that should continue to use $mydomain). Thanks for clarification -- Sent from: http://postfix.1071664.n5.nabble.com/Postfix-Users-f2.html
