On one of my servers (postfix 2.7) I need to do verp in such a way that I need to add recipient-id to envelope sender
so if sender is r...@senderdomain.tld -->ram-1...@senderdomain.tld 1111 is the numeric id of the recipient. Also I need to do VERP always , irrespective of whether the client sends an XVERP command or not. Wietse had suggested that I do a source change to do always VERP which I can easily do by making a change to src/smtpd/smtpd.c I guess the src/global/verp_sender.c -- verp_sender() function is where the encoding happens. But somehow any change I do does not seem to reflect. Is this the right file to check. Thanks Ram
