It has come to the BOFH's attention that someone is looping mail to nlnog at nlnog.net. The culprit is "mail.upc.biz" a.k.a "NLSG103.upc.biz". Mail headers for a message that bounces are shown below. The BOFH is pretty sure he can pinpoint the subscriber causing this, but he's in a generous mood, so he will give them a chance to fix before disabling them.
