Can someone > advise me how to track this down? I have no clue! Since your email is coming directly into your systems you should have evidence of bounced/rejected messages in your email server logs. However, since you use M$ as your primary server I personally don't know how to grok their logs. That is one of the reasons I would switch the MX primary to a Linux host. :-) One thing that I would also consider.... As pointed out by someone else...bounces are typically problems at the receiving end. Since you have one primary MX host the secondary will not be used unless the primary is down/unreachable. If the problem is "intermittent" it *may* be a problem with the secondary. So, I would configure my MX hosts with equal weights so both get exercised in a "round robin" sort of way. But..... After thinking about it....I think I may have found the problem.... The problem is with your secondary email server. [egreshko@misty ~]$ telnet mail2.cdkkt.com 25 Trying 216.99.218.205...
