[svlug] somebody trying to use me for spam?

[Gordon Vrololjak]

Hello,
Just wondering if anyone else has been seeing this in their logs?  (More
detailed log at bottom of email.)

ts003d0158.nyc-ny.xod.concentric.net [66.236.160.158] did not issue
MAIL/EXPN/VRFY/ETRN during connection to MTA

Best I could glean from the web was it was someone trying to see if they could
somehow use our server to relay spam.  Anyone else have insights?
They were doing it at 10pm, 1am, 2am,3am, 4am... and then they stopped.

Also, I've complained a lot to abuse at xo.com and get little more than an
automated response.  People routinely portscan from there and send me spam
quite regularly.
