It's also on njabl.org, and their web site is responding more quickly. Verizon has been contacted many times about this and either doesn't care or just doesn't know how to fix it. In fact, the MAPS page has a specific message that they must be contacted by a Verizon rep to have it removed. It will relay for anyone who gives a @verizon.net return address. == Chris Candreva -- [EMAIL PROTECTED] -- (914) 967-7816 WestNet Internet Services of Westchester http://www.westnet.com/

If an AS became insecure and could start allowing anyone to setup new netbock advertisements from it, you would filter out the AS. If it was small, you might hardcode in the valid netblocks, but when it's a large AS, you tend just to shut it all down. Such is the way with smtp. -- -Jack

It's a pretty good guess that the above mentioned server is therefore an open relay...and it's a correct one in this case. http://www.njabl.org/cgi-bin/lookup.cgi?query=206.46.170.44 http://openrbl.org/ip/206/46/170/44.htm If you're going to use a dnsbl, anybody's dnsbl, figure out how to whitelist first (or real soon after), because this sort of thing will happen from time to time. -- Jon Lewis [EMAIL PROTECTED]| I route System Administrator| therefore you are Atlantic Net| _ http://www.lewis.org/~jlewis/pgp for PGP public key_

Verizon mail server on MAPS RSS list
We've got customers trying to receive email from people using Verizon for Internet acess, and we are rejecting that mail because out013pub.verizon.net [206.46.170.44] is on the MAPS RSS list. Can't pull up the MAPS RSS website at the moment to check why. Anyone know contact info for Verizon for this kind of issue? Thanks. Josh -- Josh Gentry (Call me Gentry.)
