The following (Chinese) domains are perennial offenders (and I do mean
*years*): tom.com, 163.com, 126.com, and 263.com. Unfortunately, I
have (or have had) subscribers apparently from all of them (maybe
there's a lot of Chinese-origin spam "Created by XEmacs"? :-/), so
I've needed to filter at the list-moderator level.

That's true. If your host is already running SpamAssassin, it might
be possible to enable user filters, and then you could blacklist those
on a per-list basis (I'm not sure how hard it is to associate a user-
as-SpamAssassin-understands-it with a mailing list, though).
