XO is a giant ISP, one of at least 6 ISPs providing connectivity to the same spammers: http://spamhaus.org/SBL/sbl.lasso?query=SBL5056. Rather than chasing down entire /24s yourself, which is prone to error and frequent change, you'll be much better off using some kind of RBL query (Declude, IMGate, etc.). I admire your efforts in this arena, but for a few bucks you could have software do much of this for you. -Sandy To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
