I forgot something important to mention. Maybe thats the source of our Problem? Our Mail-Provider is the actual target of the mails. We fetch the mails from it with fetchmail and pop3. Fetchmail then sends the mail to our intranet mails system. When fetchmail receives the mail with pop3, the return-path already matches the destination address of the mail.

But now a problem arised and I was not able to solve it myself or with help from the docs. We are using sender_bcc_maps, because we want any mail that is sent from one of our employees to be copied to a central mail account. Since a few month our mail provider delivers us mails that are addressed to one of our employees, where the return-path header ist set to the mail address of the receiving employee. The mail is now copied to our central outgoing account. We don't want that. How does the sender_bcc_maps mechanism exactly works? Does it react on mail body header fields like return-path? Is it in detailed documented somewhere? Can we prevent sender_bcc_maps from reacting on the return-path field? If not, how can our problem be solved? Should we use some kind of filter for incoming mails that removes the return-path? Thanks in advance for any help template
