Hello, I am setting up an email server using postfix.
I use an internal domain for internal mails, and address rewriting for outgoing emails. In main.cf, the parameter smtp_generic_maps = hash:/etc/postfix/generic and a file "generic" with lines like this: [email protected] [email protected] As fas as I know, it works, since outgoing emails are sent with the right sender's external address. I also use sender_bcc_maps to send a copy of all outgoing emails. In main.cf, the parameter sender_bcc_maps = hash:/etc/postfix/sender and a file "sender" with lines like this: [email protected] [email protected] I am pretty sure that this mechanism worked for a time, but I recently noticed that it isn't working anymore. The problem is that the address rewriting sets the sender's external address AFTER the sender_bcc_maps adds the bcc destinations. So, it never detects an email from @mycompany.com, because all of them are sent by @mycompany.local. I'm looking for a way to have a copy of outgoing emails and sender's address rewriting at the same time. I have already tried using regular expressions, but I have failed so far (i am still trying though). Any ideas will be welcome. Thank you indeed.
