No kidding, dude. I've only been keeping track for a few weeks. Is
anyone awake behind the wheel over there?

  The question is: is that a knee-jerk reaction to them getting clobbered by
  spam, or maybe a knee-jerk reaction for receiving "too much" mail ABOUT
  their customers to abuse () att net ?

  Example: 12.158.240.0/23, 12.42.172.0/22, 12.158.224.0/23, 12.158.234.0/23,
  12.158.236.0/23:

  Jan 24 16:11:03 sonet sendmail[11117]: NOQUEUE: ruleset=check_relay, arg1=if1.dlyforyourinfo.com, 
arg2=12.158.240.237, relay=if1.dlyforyourinfo.com [12.158.240.237], reject=550 NETBLOCK for CBB/cotennet.com - access 
for jpmailer.com denied - perpetual mail to non-existing users - Spammers must die.

  Upon complaint re: this spamhaus continuing to connect here:

  The original message was received at Fri, 24 Jan 2003 16:11:09 -0500 (EST)

  (a temporary failure due to renumbering)
  Rejecting on broken or non-existing DNS will probably reject mail from
  more than 15% of all mail servers on the Internet - guaranteeing a
  false positive rate not even matched by the combined 6 DNSBL's I
  use - cumulative and with hard 5xx rejects. AT&T on the other hand,
  will use DNSBL's when the first snowball emerges from hell unscathed.

  Makes you wonder if noc () att net is missing a lotta mail today -
  "gee, za eanternet w0rcks zplend1d todey, duznt eet!" -
  think of http://www.despair.com/ap24x30prin.html :)

  Last but not least, Level3's tolerance of spamming customers has nothing
  on AT&T's ignorance of reports of DoS attacks in the form of address forgery
  committed by their spamming customers, or on behalf of said customers, despite
  notifying them by fax of such activity. That, and the mindless blather
  you receive back from abuse () att net on very rare occasions when you complain
  about their customers hitting your spamtraps (dead users, rejects):
  "please forward the header and full body of the spam you received".

  Next: "please call 1-900-ATT-ABUSEDESK, get charged $5 for the call,
  and use the authorization code given to you in the subject line of
  your complaint to guarantee that your message is not shoved into /dev/null"
