In reply to message 1 from Andrea Turco
I suspect that the problem may be something else. Are you sure that the mails are only recognized as spam when you do not set the Return-path address?
The Return-Path address is virtual. I mean, the mail protocols ignore that address. The mail message classes just look into it to set the address where undelivered messages are returned.
Maybe when you do not set the return-path address, the messages bounce to a mail address that you do not have access, rather than being recognized as spam by the recipient mail system.
