It's connecting to the server it should based on the DNS information it is provided. You may have a problem with your DNS infrastructure which is causing the proper results to not be returned. If your ISP's DNS servers are the forwarders you are using for your internal DNS, these could indeed be the problem. You could ask them for a better/different set of forwarders.

For some reason my exchange server randomly decides to send mail to the wrong server - Here's one example; User sends to her earthlink account; connects to 209.86.93.228 result OK 2008-08-26 14:28:49 209.86.93.228 OutboundConnectionResponse SMTPSVC1 FCI-EX - 25 - 250+1kxZxmZz3Nl34g0+Message+accepted+for+delivery 0 SMTP - - 2008-08-26 14:28:49 209.86.93.228 OutboundConnectionCommand SMTPSVC1 FCI-EX - 25 QUIT - 0 SMTP - - 2008-08-26 14:28:49 209.86.93.228 OutboundConnectionResponse SMTPSVC1 FCI-EX - 25 - 221+mx-pigeons.atl.sa.earthlink.net+closing+connection 0 SMTP - - Later on in the day she sends another email; my server decides to connect to 209.86.93.201 - result Not OK 2008-08-26 18:09:26 209.86.93.201 OutboundConnectionResponse SMTPSVC1 FCI-EX - 25 - 550+Authentication+required.+Help+at+http://www.earthlink.net/go/emailsetting s 0 SMTP - - Nslookup tells me; mx1.earthlink.net internet address = 209.86.93.226 mx2.earthlink.net internet address = 209.86.93.227 mx3.earthlink.net internet address = 209.86.93.228 mx4.earthlink.net internet address = 209.86.93.229 So I know why its failing - I know what it is going wrong , but WHY is it doing this and how do I correct it Could my ISP's DNS servers be on the fritz? And its not just happening with earthlink- thanks Jean-Paul _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/read/?forum=exchange To subscribe: http://e-newsletters.internet.com/discussionlists.html/ To unsubscribe send a blank email to [EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
