lamers looking for relays

[ronnie gauthier]

The spam vigilanties are as bad as the spammers themselves. They are scanning when and where they want and blocking without probable cause. They also refuse to unblock legitimate addresses because they are within a block owned by spam tollerant service providers. Their answer is to tell you to move to another provider and you are staying blocked. I know it can cut down on spam but I just have no use for assholes who act as god without also being able to walk on water and feed the homeless multitudes.

The njabl.org folks are taking over where ORBS and friends left off,
scanning machines for relays without any reason other than they can (e.g.
they haven't any spam from the systems to justify a relay test).

That isn't to say that there aren't a buttload of spammers looking for open
relays, we see hundreds of attempts per day in our smail-3.2 logs (which we
enter in our local RBL to prevent them from ever sending anything to our
servers in the future).

The best open relay I know of is relays.visi.com.  They only list sites
that have actually sent spam.  We forward several hundred IP addresses a
day to them from our spamtraps.  They then do a test to verify that the
host is truly an open relay, and list them appropriately.  We block about
100,000 connections a day, 75,000 of which are listed by them.

Government spending?  I don't know what it's all about.  I don't know
any more about this thing than an economist does, and, God knows, he
doesn't know much.
