Hi Chuck, I went through the same process for the same problem. I had to change my server pick a few weeks later when the one I had picked stopped working. First time I tested all of the 16 servers 6 weren't working. Next time 8 weren't working.
Drives me nuts that my customers blame me when mail doesn't get to hotmail users when they have MX records still pointing to nonresponsive servers. ~Katie -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Charles Frolick Sent: Thursday, July 22, 2004 5:23 PM To: [EMAIL PROTECTED] Subject: [IMail Forum] Hotmail.com delivery issue Wondering if anyone else has run across the sam and has a more automated prevention. Apparently the way hotmail.com/msn.com lists their MX servers is an MX to roundrobin hostnames, well many of their servers were unreachable and queuemanager was only attempting to down servers, and would not refresh or try others. I finally had to add one of the up servers to my hosts file to get mail flowing to them (big issue for a busy ISP server, had over 5000 messages in queue at one point). How I know several server were not responding: I tried connecting to the same servers via telnet and the following from DNSReport.com, which shows at least one server from each MX roundrobin group down, and Imail kept picking the lemons. Step 1: Try connecting to all of these (in the order as returned by the DNS resolver, per RFC1123 5.3.4): mx2.hotmail.com. - 65.54.190.7 mx2.hotmail.com. - 65.54.190.50 mx2.hotmail.com. - 65.54.252.230 mx2.hotmail.com. - 65.54.166.230 mx3.hotmail.com. - 64.4.50.179 mx3.hotmail.com. - 64.4.50.239 mx3.hotmail.com. - 65.54.167.5 mx3.hotmail.com. - 65.54.253.99 mx4.hotmail.com. - 65.54.190.179 mx4.hotmail.com. - 65.54.190.230 mx4.hotmail.com. - 65.54.253.230 mx4.hotmail.com. - 65.54.167.230 mx1.hotmail.com. - 65.54.252.99 mx1.hotmail.com. - 64.4.50.50 mx1.hotmail.com. - 64.4.50.99 mx1.hotmail.com. - 65.54.166.99 Step 2: If still unsuccessful, queue the E-mail for later delivery. ---------------------------------------------------------------------------- ---- Trying to connect to all mailservers: mx2.hotmail.com. - 65.54.190.7 [Successful connect: Got a good response [250 [EMAIL PROTECTED] ]] mx2.hotmail.com. - 65.54.190.50 [Could not connect: Could not connect to mail server (timed out).] mx2.hotmail.com. - 65.54.252.230 [Successful connect: Got a good response [250 [EMAIL PROTECTED] ]] mx2.hotmail.com. - 65.54.166.230 [Successful connect: Got a good response [250 [EMAIL PROTECTED] ]] mx3.hotmail.com. - 64.4.50.179 [Could not connect: Could not connect to mail server (timed out).] mx3.hotmail.com. - 64.4.50.239 [Successful connect: Got a good response [250 [EMAIL PROTECTED] ]] mx3.hotmail.com. - 65.54.167.5 [Successful connect: Got a good response [250 [EMAIL PROTECTED] ]] mx3.hotmail.com. - 65.54.253.99 [Could not connect: Could not connect to mail server (timed out).] mx4.hotmail.com. - 65.54.190.179 [Could not connect: Could not connect to mail server (timed out).] mx4.hotmail.com. - 65.54.190.230 [Successful connect: Got a good response [250 [EMAIL PROTECTED] ]] mx4.hotmail.com. - 65.54.253.230 [Successful connect: Got a good response [250 [EMAIL PROTECTED] ]] mx4.hotmail.com. - 65.54.167.230 [Successful connect: Got a good response [250 [EMAIL PROTECTED] ]] mx1.hotmail.com. - 65.54.252.99 [Successful connect: Got a good response [250 [EMAIL PROTECTED] ]] mx1.hotmail.com. - 64.4.50.50 [Could not connect: Could not connect to mail server (timed out).] mx1.hotmail.com. - 64.4.50.99 [Successful connect: Got a good response [250 [EMAIL PROTECTED] ]] mx1.hotmail.com. - 65.54.166.99 [Successful connect: Got a good response [250 [EMAIL PROTECTED] ]] Thanks, Chuck Frolick ArgoLink.net 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/ --- [This E-mail scanned for viruses by CENTRIC INTERNET SERVICES] --- [This E-mail scanned for viruses by CENTRIC INTERNET SERVICES] 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/
