   Thank you, Alan!! That was exactly the problem. I'd stared at that
code for hours, and even rewrote it once, and hadn't caught that
problem.

   Yes, looking into the mimedefang-filter man page, I see that. I got
the code I used from the Wiki, so I suppose the Wiki pages with the
example filters should be updated.

   I've added them to my toolbox. Thanks.

   Yes, I merely obscured the addresses of the hosts that don't talk
directly to the 'Net.

   What if the address is *not* enclosed in [ ]s? Does one merely delete
the [ and ] from that test, or is it more complex than that?

   Seems to be working fine (I tested it by telnetting in from an
external host), and as I noted above, I got the snippet from the Wiki.

   Yes, the -l option is part of the invocation.

   Thank you, Alan, James and David. MIMEDefang is working well right
now. Just basic filtering in place, but I want to add more.
