MyDoom.O sneaking through!

[Chris Yuzik]

Hi everyone,

I'm running the latest version of MailScanner (just updated yesterday)
and for some reason, MyDoom.O is occasionally getting through. According
to my logs, in the last week, I've had 11,001 messages with MyDoom.O
blocked...but I know that some of them are getting though because I had
someone send me a zip file that they received today and the virus was
completely intact and waltzed right through the system.

How do I troubleshoot and fix this?

Thanks,
Chris
