Hello List, I've found some more info, but still no solution to this problem. qmail-verh requires a Return-Path: line to say this: [EMAIL PROTECTED] But with virtual domains using vpopmail, the Return-Path: line comes through with this: [EMAIL PROTECTED] m The extra "uservirdomain.dom" seems to be breaking the verh substitution. Sending an email through the ezmlm software to remote addresses creates a Return-Path: address in the proper format. Only when sending to a Local, vpopmail address does it add the extra uservirtdomain.dom to the Return-To: line. How does qmail write the Return-Path: header, and what does it have to do with virtual domains, and the users/assign file? Thanks for any help. Russ
