XmonSmtpAgent: Failed to process ON END OF HEADERS event

[davidenco 1]

Since installing ESMX v7, the following events are being logged into the Event Log on a regular basis. Any ideas why?

Hi davidenco,

The error in logs is caused by an exception while parsing "Received:" headers. We will address the issue in next hotfix of EMSX.

Could you PM me a procdump file(s) capturing the exception? It would help us to track it down:

procdump -ma -e 1 -f "nullreferenceexception" edgetransport.exe

That command doesn't work. I have put procdump.exe into the V15/Bin folder and run that command but it just shows the help information for procdump. Any ideas?

[filips 43]

I updated the answer - there was a problem with encoding of some characters...

[davidenco 1]

Thanks, how much output do you need? I am seeing unhandled exceptions, format exceptions and so on right now.

I have sent you a PM with the dump output as requested.

This issue should be fixed in ESET Mail Security for Microsoft Exchange Server version 7.0.10020.0
