Excellent, although I have been a little leary to use too many regex's due 
to fear of the unknown.  What, please, is the key to that one that 
identifies a uuencoded email?

I believe I could get away with that too.

Correction, Outlook Express, potentially the most common email client in the 
world, doesn't use uuencode by _default_.  It is very easy to turn it on and 
I do see email come through that appears to be from valid sources, with 
uuencoding.

TFF (thought for Fritz) - It would be heavenly if there was a way to block 
uuencoded emails in the "Attachments and Viruses" section with a separate 
error message to indicate uuencoded emails are not accepted by way of 
policy.  This would allow us to reject these as we reject other banned 
attachments even if bombRe was in test mode, thus saving the need to virus 
scan them.

Just an idea,

Thanks for the info,
