Return-Path can't be reliably set on the source system; it is commonly set by the destination system using the value from MAIL FROM obtained during the SMTP transaction. You may be better off not using mail() and instead exec'ing a copy of sendmail (or equivalent) with the "-f" flag (or equivalent). Such as: sendmail -faccounts@talismanmarketing.co.uk You can do this in a few different ways, but it's not any different than opening any other process and piping data to it. -dan -- If the police arrest a mime, do they tell him he has the right to remain silent? -George Carlin
