Forward = Spoofing?

Code:

Return-Path: <mailing-bounces@glcr.lu>

Why does this mail get accepted while the forward one does not?

Usually the mailing list server sends the "mail from" command with it's own address "mailing-bounces@glcr.lu", or a something like "bugtraq-return-identifier@bugtrack.com"
In any case the mail comes from another domain (glcr.lu in this case), and it's send to the destinations within pt.lu, with just the headers that state the original sender of the mail, so you can see it fine from your mail reader, and receive, since the mail from states that is being sent from another domain.

Unless you create a new mail originating from you with an temporary address from your domain (that's what SRS is about) to keep track of that mail in case you receive a bounce, you won't be able to forward to pt.lu

Hope it helps
