[Nlnog] LART time.

[NLNOG BOFH L]

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.
