(second reply)

Given the addresses that delivered, I looked through TMDA's pending queue
(which still has all the messages in question) for those messages.  I
sorted them by size and looked at the largest ones (i.e., I was looking for
viruses that I challenged).  I found:

* Two viruses that were originally forged FROM my domain and BOUNCED to me
by someone (who then got my challenges).

* Seven obvious spams.

* One challenge from a system I haven't seen before (replying to a spam
that was forged from my domain).  I'll add its identifying characteristics
to my procmail rules and stop challenging it.

* Three messages that consisted ONLY of a JPG, which contains cyrillic
characters and one legible email address.  No idea what that is.

I stopped looking when the feeling of "wasting my time" overtook the
feeling of "I might find something interesting."  By that time I was
looking at messages with sizes less than 13K.

So, basically, the numbers I posted earlier don't include any challenges I
sent in response to viruses--but they might include a couple of challenges
I sent in response to a response to a virus.  My search wasn't really that
great since (1) I found 404 matching emails for the 320 delivered
challenges, (2) I didn't think to throw away the most recent (which had
been virus checked) until I was a ways into my search, and (3) I didn't
really cross-check whether the messages found were ACTUALLY challenged or
merely held.  Still, I feel pretty comfortable saying that I didn't
challenge a virus.
