I have two email adresses: a...@domain.tld and b...@domain.tld Only a...@domain.tld is registred with several mailinglists. But the user b...@domain.tld is the one I want to use. So I need to find a way to rewrite the sender address (b...@domain.tld) to a...@domain.tld BUT only in case the receiver is us...@maillist.tld. If the email has not to be sent to the maillist no rewrite in senderaddress should be performed. Is there a way in Postfix to do such a conditional sender rewrite? If it's not then no problem as I will register b...@domain.tld with the maillists. I just wonder whether this would be technically possible with Postfix or not.
Thanks a lot for all tips/hints Cheers tobi
