Some mail delivery agents will add a From line (which is different than the From header) on final delivery that includes the envelope sender address (or the rfc 821 encoding of it). But that line isn't part of the message until final delivery. There is a chance that this is the check being used to thwart the original poster. But it's also possible that the mailman server is firewalled. If his university has a vpn or if he has machines he can into remotely, he might be able to work around that limitation. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
