[Mimedefang] Rejecting some recipients

[Jeff Grossman]

I currently have MIMEDefang setup on a Linux box running as a gateway to my
mail server.  In my mimedefang-filter, I have some code which will reject
certain recipients who are not allowed to receive outside e-mail.  I have
about 15 e-mails accounts set up in this rule.  It works for the most part.
When somebody sends an e-mail to all of those e-mail addresses, the filter
usually times out and will end up allowing some of the e-mails through.  I
am not really sure why.  I have made changes to my timeout values in
Sendmail, but still it times out.  The e-mail in question this time was
pretty small.  The size reported by Sendmail is 28139.  Here is one of the
errors:

I was thinking of using my access database to help me instead of MIMEDefang.
I don't know enough about the access database.  If I put each of e-mail
address that I don't want through with a REJECT, can I then add a
*@domain.com with an OK below that?  Will it reject just those few e-mail
address, but allow the rest through for further MIMEDefang processing?
