The particular message I was looking at didn't have an empty sender, but by
that point, the host was already marked as past its final cutoff time in
the retry hints file.

Could, then, a message with an empty sender failing after 4 hours cause the
host to get marked as 'past final cutoff' in the hints db even though other
messages have a final cutoff time of four days? That would certainly
explain pretty much everything I'm seeing, and I have a sneaking suspicion
that the first time I saw this behaviour (on a different server) was not
long after I intorduced the "senders=:" retry rule.

Hmmm. I think I'll comment out that rule for the time being and see if it
makes any difference.
