Here's where this gets interesting. ;-)

I myself subscribe to this list, have the nodupes bit set, and see
"Receive your own posts to the list? Yes" in my configuration page.  I
receive copies of my own posts.  Would that be because I'm the owner?

The other subscriber *also* has the nodupes bit, also sees "Receive your
own posts to the list? Yes" in his configuration page.  He *doesn't*
receive copies of his own posts, yet everyone else does.

Understood, thanks.

Actually, I re-analyzed the logs just now and it turns out that there
had been an unsubscription between the time that this message was
relayed and the time that I ran list_members.  Therefore, the recipient
count should be considered to be 57, which accounts for the fact that
his post wasn't sent back to him.

Possibly, but I can't help but thinking that the problem lies in
Mailman-space, since Postfix would at least record an attempt, yes?

No bounce recorded.

Highly doubtful, since the message is not getting past my MTA. ;-)

Thanks again.
