Postfix VERP works in a different way. It puts the complete recipient name and domain into the sender address, instead of a short code that identifies the recipient. Is there a problem with sending VERP as implemented: originalsender = sen...@senderdomain recipient = recipi...@recipientdomain verpsender = sender+recipient=recipientdom...@senderdomain > Also I need to do VERP always , irrespective of whether the client sends > an XVERP command or not. You could use an SMTP proxy that always sends XVERP, as suggested by Victor. There are lots of examples if SMTP proxies in PERL. Wietse
