I thought it did, but I just got a message that seems to indicate that
it didn't. Someone emailing me got this error:
Message delivery to the host '18.104.22.168' failed while delivering to
the remote domain 'domain.com' for the following reason: The semaphore
timeout period has expired.
I checked my logs, and the virus scan took 12 seconds. Most of that
(11s) was scanning the msg file, so I assume it took another 11s to
ripmime it before calling clamav. I guess 23 seconds is a long time to
wait for a response after ending the DATA part of an SMTP conversation.
It could just be a bad timing thing where the other end drops the
connection and simscan replies that it was received OK before it knows
the connection closed.
It might need some further testing by the simscan developers to find
additional failure points.
Interesting. Do you have any idea what the remote email server was ?
(The actual MTA I mean).
