Coming back from my vacation, I had to discover that some losers
(who, no doubt, had something to lose as far as their hijacked IP space
is concerned) have attempted to DoS the MX for pac-rim.net/spamshield.org
by sending a few 100,000 spams with randomized @pac-rim.net return
addresses around June 25/26th, and us seeing 10,000's of bounces
generated by misbehaving mail hosts that bounce to MAIL FROM: addresses
sometime after their mail back-end decides that the recipients don't
exist (nice AOL-style abuse amplifier, just un-AOL-like unthrottled).
I got hit by this same joe-job MO last week:
http://mrtg.snark.net/spam/
Randomized return addresses @snark.net; relayed through all sorts of
open proxies and relays. I have a couple thousand bounces, if anyone's
interested in analyzing the headers further.
It looks like someone's playing games with the folks on NANOG that
actually care about mail abuse.
We're losing the battle, aren't we?
