[Mimedefang] Skipping Defang for Outgoing Messages

[Anthony Slay]

My users are having the problem of waiting a minimum 4 seconds for an 
outgoing mail to be sent off and to some of them, this is annoying.  We use 
Eudora 3.0.5 to 5.1 and it's not really a problem with the 5.1 users 
because sending is done in the background.
I understand that MIMDefang/Sendmail does not differentiates form incoming 
and outgoing messages.  At least, I think that's the case.  I took a look 
at the stream-by-domain-filter example and this looks like the best choice 
right now but that will leave a hole in our protection (sort of).  Does 
anybody know if there a way to skip MIMEDefang for all outgoing messages?

Also, is there a tool to append quarantined messages to a unix user's 
mailbox?  I've tried using cat but that just make an invalid mailbox entry.
