email passes in ORF but never hits Exchange RSS Back to forum


I'm running ORF 5.3 and Exchange 2010. I have emails that are passing ORF but never hit our Exchange server. We also run Kaspersky on the Exchange server but I have white listed the sender email in question. Also when Kaspersky stops an email I can see that in Exchange. I'm at a loss where these emails could be going? Any ideas where to look or how to trouble shoot would be appreciated.

Hello dan.schell,

Since ORF is letting those emails pass, I suggest you check the logs and settings of the other mail-security agents you have enabled on the Exchange server. Start the Exchange Management Shell on the ORF server and run the "Get-TransportAgent" command. Test the mailflow by temporarily disabling filtering agents that have a higher priority than the "Vamsoft ORF SMTP Receive Agent", one-by-one and try resending the problematic email(s) each time. That said, more often than not, we find that the culprit is the Content Filter Agent of Exchange ( so you might want to disable that agent first:

If the above does not help, check the configured Transport Rules (aka. Mailflow Rules) of Exchange:

The following forum thread might prove helpful to you as well:
