Here are two more ideas:

1. A bit to indicate that the recipient doesn't want to receive anonymous
e-mail if it contains the strings "fuck", "piss", "shit", "cunt", etc. Of
course, this can be circumvented with "f*ck u c*nt", but it shows good faith.

2. Limit the maximum number of e-mails that one remailer can send to
this address in a 24-hour period. I'd suggest using 2 bits:

00 - unlimited
01 - 10 / day
10 - 100 / day
11 - 1000 / day

with the default being 10 / day for addresses not in the database and also
for addresses added to the preferences database w/o specifying otherwise.

Thus, if you do expect to receive more than 10 anonymous e-mails / day via
one remailer, you must add your address to the database, not necessarily
blocking anythihg, but specifing that you want 100, 1000, or an unlimited
number of messages in a day.

When the count goes over the limit, a single e-mail is sent to the recipient
saying that there may be an attempt to mailbomb him, that some of his e-mail
was being junked, and that he can change the settings if he wants to.

This should prevent the kind of abuse you've described.
