And if you want to send me the full bounce message with headers off list I will certainly look harder and can tell you for sure.
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 AT&T for mail forwarding. So if the message was "Cannot find OUTBOUND MX Records", then it's something on AT&T'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.us<mailto: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.net<mailto: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.us<http://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?
