I've had the same issue with hotmail when email originates from 208.127.57.0/24. any mail sent from a server within that netblock is properly accepted by hotmail, given a queue id, but disappears and is never delivered. if anyone from hotmail has a clue as to what's going on, it would be appreciated. thanks much ... ----- Gabriel Kuri | Sr. Network Analyst Instructional and Information Technology Division California State Polytechnic University, Pomona http://www.csupomona.edu/~iit | +1 909 979 6363 > -----Original Message----- > From: [email protected] [mailto:[email protected]] On > Behalf Of Jeroen Wunnink > Sent: Wednesday, April 25, 2007 11:22 AM > To: [email protected] > Subject: Hotmail blackholing certain IP ranges ? > > > Does anyone have a clue why hotmail is appearantly blocking > certain IP ranges ? > > I provided a new server for a customer in his own IP subnet which is > a part of a /20 we announce, but for some reason all mail sent to > @hotmail.com addresses disappears. > > He has another server in a /24 we announce which is still part of > another network and that works like a charm. > > None of our subnets are blacklisted in any spamfilter I can find, so > i'm a bit puzzeled on what's up here. > > If any hotmail netadmin is reading this list, can you please check if > 81.26.212.0/26 is blocked in any way (It's part of 81.26.208.0/20 > originating from AS39556) > > According to the mailserver logs all the mail is properly accepted by > the hotmail relays, never to be seen again after that. > > > > Met vriendelijke groet, > > Jeroen Wunnink, > EasyHosting B.V.
