Running Host Monitor 8.64 on Windows 2003 Server. We have an Exchange 2003 server that hosts mailboxes three hops away from the HM server, through one firewall.
The test is set up to send an email to a remote address and then an automatic forward sends it back to the Exchange server. The test works fine mostly, but once in a while (twice a week) we get a "not delivered" alert and a status of Bad. When we check the Exchange mailbox, the message is there but HM just didn't pick it up. When we restart the HM service, then it will successfully log on to the mailbox and grab the email, and then the status clears to OK.
We have tried troubleshooting all of the networking in between the HM server and Exchange, but everything else is good. Is this a bug?
Mail Relay test
Set to Alert when incoming mail server does not receive mail before next checking cycle. We have performed some troubleshooting on this, and we do see that the email has made it back to the Exchange mailbox. It's just sitting there but HM does not pick it up for some reason. When we restart the HM service (or in some cases close the console application and then start the application up again) it will then see the email, download it, and change status to Good.
Not exactly. When you restart HostMonitor it just removes old e-mail without checking when it was delivered or what exactly test item generated this e-mail...
Could you please send 2 copies of e-mail to support@ks-soft.net (one e-mail that was correctly detected by HostMontor, another one that was ignored)?
Do you have installed some real-time antivirus monitors? May be they modify e-mail body?

Looks like one of these e-mails was modified by some 3rd party software, it included 2nd copy of "From", "Sent", "To" and "Subject" fields using TAB character in these lines. This leads to the problem...
Do you know what software modifies e-mails in such way ?
Probably MessageLabs Email Security System? But as I see both e-mails were scanned by this software while extra subject line was added to one of them...
