I got a 60MB mailbomb the other day which didn't bother me a least bit.
That wasn't done via the remailers; it came via worldnet.att.net's open
smtp server. The initial form letter asking for permission should warn
about the possibility of their getting a large amount of crap. However
it's just as easy to get a throwaway account and mailbomb someone via
that.

I say: discard (don't keep) e-mail for folks who haven't explicitly
unblocked themselves;
treat "unblock" as "unblock everything and face the consequences".

Letting the user impose some sort of constraint on the size of the
e-mail being remailed is actually a dumb idea:
* any half-decent mail handler should do it on the user's side
* they can be mailbomed by a 1000 little messages
