That's sort of the problem.  The rest of it is that the address was at
a domain that was abandoned years ago, and the entire domain is now a
spamtrap.  The address bounced for quite a while, so normal list
bounce processing would have removed it.

If this list is like many other old mailman lists, it does no bounce
pruning at all, with predictably unfortunate results.
