Re: [ALUG] Forcing "Return-Path:" in sendmail

I want to find a way to *force* sendmail to include a specified "Return-Path:" header in mail it sends to a remote [E]SMTP server.

No, you don't. Return-Path is only added at final delivery.

Specifically:

Return-Path: Ted.Harding@nessie.mcc.ac.uk

rather than the header it computes automatically.

What you actually want is probably the -f option to sendmail (and its workalikes). -- http://www.greenend.org.uk/rjk/
