Any message that fails the TNEF timeout is considered an unparsable TNEF
attachment and is quarantined.

When a batch of messages exceeds the Virus Scanner Timeout, the messages
are scanned individually (with the same timeout value) to see if one of
them on its own causes a timeout. If there is one (or more) individual
messages found to cause a timeout, these are marked as "Denial Of Service
Attacks" and are quarantined.
