There's an example, by the way, of this exact technique right here - python-list@python.org sends mail to me with an envelope-from of "python-list-bounces+rosuav=gmail....@python.org" - which passes SPF, since python.org has a TXT record designating the sending IP as one of theirs. It doesn't matter that invalid.invalid (your supposed domain) doesn't have an SPF record, nor would it be a problem if it had one that said "v=spf1 -all", because that domain wasn't checked. Mailing lists are doing the same sort of forwarding that you're doing. (Apologies to those who read this as a newsgroup, for whom this won't be as parallel an example. But it's still the case, just not for the posts you receive.) ChrisA -- http://mail.python.org/mailman/listinfo/python-list
