36K backscatter rejects from hotmail yesterday but only 2K from
AOL. AOL has really got their act together compared to hotmail,
verizon, comcast, and the like.
May 18 00:00:05 mx1 postfix/smtpd[11977]: 6F8F315DC0: reject: RCPT from mc1-s21.bay6.hotmail.com[65.54.163.161]: 550 <>: Recipient address rejected: User unknown; Probably forged by Alan Ralsky; from=<> to=<> proto=ESMTP helo=<mc1-s21.hotmail.com>
It was 80K daily from hotmail till I dropped the MX records for 4
of the domains being forged. If anyone would like to test their
capability to reject 1+ million a day I can point the MX records
to your servers. :-)
