RE: DNS Issues
Are you using mxlogic as an outbound mail relay? If you are, is there any chance recipient's mail domain used to be a customer of mxlogic? If they used to be a customer of mxlogic, and then moved to ATT, then while they were a customer of mxlogic, their MX records would have pointed to mxlogic. The mail servers at mxlogic would have their own route tables for forwarding the mail on to the Madison servers (they couldn't use MX, or it would be a mail loop). If they didn't get all the entries cleared out of their smtp route tables, I believe it would cause the symptoms you describe.

RE: DNS Issues
Yes. I don't know, but anything is possible. Never thought of that before but I can see where you're getting at. I've asked the users to let me know the next time they get a bounce message so I can look at it a little more. Thanks for the suggestion Rob.

If you are, is there any chance recipient's mail domain used to be a customer of mxlogic? If they used to be a customer of mxlogic, and then moved to ATT, then while they were a customer of mxlogic, their MX records would have pointed to mxlogic. The mail servers at mxlogic would have their own route tables for forwarding the mail on to the Madison servers (they couldn't use MX, or it would be a mail loop). If they didn't get all the entries cleared out of their smtp route tables, I believe it would cause the symptoms you describe.

So I believe your statement that ATT is blowing this up is correct. From: Bonnie Pohlschneider [mailto:bpohlschnei...@crsi-oh.com] Sent: Friday, January 21, 2011 3:19 PM To: MS-Exchange Admin Issues Subject: RE: DNS Issues So if I'm reading this right... Their mail is not being received by www or smtp.co.madison.oh.us because The MX record shows that they are using ATT for mail forwarding. So if the message was Cannot find OUTBOUND MX Records, then it's something on ATT's side rather than on Madison Co's side?

Some names have been changed to protect the innocent :) Having problems with users sending mail to one domain in particular. They are getting an intermittent bounce back message stating: john@co.madison.oh.usmailto:john@co.madison.oh.us: 553 Cannot find OUTBOUND MX Records for domain (co.madison.oh.us). This message is coming from mailer-dae...@p02c11o149.mxlogic.netmailto:mailer-dae...@p02c11o149.mxlogic.net so I know that it's not on our end. I had our independent contractor look into this, and had MxLogic Support look at it, and they both confirmed that the issue is on co.madison.oh.us side and basically nothing we can do about it. Since users don't like to hear sorry I can't help you, I did some more digging and decided to ping smtp.co.madison.oh.us. IP address resulting was 140.174.119.1. Then tried ping -a 140.174.119.1, to make sure we're resolving, and I'm getting www.co.madison.oh.ushttp://www.co.madison.oh.us not smtp or mail. I'm thinking this is causing the issue but have been unsuccessful at persuading the IT department on the other end to work on this. Anyone have any other ideas?
