I am doing exactly the same as you are.

This is the same here again, however 2.41 is released now, it's easy to
install over your current setup.
(since you installed the ports version of MD 2.39, you can install the
source version of 2.41 and everything will work fine)
You didn't mention your perl version?  I installed 5.6.1 (hearing of many of
my favorite programs requiring this or newer).

I took this same approach, ClamAV can be a little trouble installing, it
requires a lot of additional requirements.  Once you get past that, it seems
to do the job great for us.  It all depends on how you install (ports vs.
source).

Sounds like me again, show me some code and I can tweak it all night ;)  Two
weeks ago I never seen FreeBSD before, today I am using it for inbound mail
relays.

Being only 2 weeks into this project, I seem to understand clamd is a daemon
version of clamav.
With 2.4x of MIMEDefang, it uses multiple virus scanners if they are
installed, but does this apply to
clamav & clamd?  Will it use one if the other fails?  Hopefully someone else
can clear this bit up for both of us.

Improvements in 2.4x versions use all virus scanners by default.  I'm not
sure how this works with clamd & clamav (clamscan?).

I'll try and help as much as I can, now that I am able to understand this
program, I would like to help others do the same.  Blocking during the SMTP
session is the answer to all my problems and I am so greatful this program
allows me to do that!  Thank you to those in charge of development!

I have a graph of our e-mail traffic on the bottom of our homepage (in my
sig).
