How to deal with extremely high spam levels

[Bob Vincent]

Bogofilter is apparently designed for the situation where the number
of spams per day roughly equals the number of non-spams per day.

In my situation, the ratio exceeds 100:1.  In the two weeks I've been
re-training bogofilter, I've collected:

  Correctly filtered Ham: 101
  Unsures registered as Ham: 26
  Correctly filtered Spam: 1067
  Unsures registered as Spam: 14177

Part of the reason for my unusually high spam-load is that I'm
receiving catch-all emails for several domains.  Part of the reason is
that my email address is listed in several places on the internet.

I am unwilling to change email addresses or remove my catch-all
accounts.  I would rather just filter the crap out at the server.

However, at this rate, it will take nearly a year to collect enough
non-spam to run bogotune.  I'm not willing to wait that long.

If Bogofilter is inadequate to this situation, are there any
recommendations for how to properly deal with it?

Thanks,
