Well, we finally nailed it down to a problem with McAfee/MxLogic. Gotta love their response...

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?
