I have been changing my mailing addresses from "example.com" to sub domains - say "mail.example.com" to configure no-reply addresses there. I use "sendmail -f [email protected]" to send emails to make sure the Return-Path is correct. My mail delivery chain looks as follows:
SENDING SERVER --> relay_server --> gateway out For unknown to me reason when my email reaches the gateway that send them out, I see that the "from" address is already altered in the postfix log file to "[email protected]". This is also what I see in the detailed message log when it reaches its destination. named_attribute: log_ident=E542AA0188 named_attribute: rewrite_context=remote sender: [email protected] Any clues what could cause that?
