Forefront detecting all emails as virus, "Exceeded Realtime Timeout"
Posted on 2009-04-05
All our internal emails that are being sent are coming up with the following Quarantine Message:
The original contents of this file has been replaced with this message because of its characteristics.
File name: "Body of Message"
Virus name: 'Exceeded Realtime Timeout"
Even if emails do not have any attachments, ie. just plain text the above error is sent to the recipient of the message.
Our Exchange 2007 mailbox store also has MS Forefront installed on that box
I've checked for the following things:
-Disabling each of the 5 default Scan engines
-Restarted Forefront Services
-Increased Max Container Scan Time parameter to 4 - 10 mins
all which had no effect on stopping internal messages from being quarantined.
For the interim I've changed in (Forefront's General Settings) the Realtime Scan Timeout Action parameter and have set it to Skip: detect only to at least allow for mail to flow.
I'm a bit uncomfortable with leaving this setting on.
Has anyone experienced this before? I'm not too sure on how to resolve this issue, any advice would be greatly appreciated.
