This is the patch that we used with Bill's toaster and it was very
effective in limiting the damage from hijacked email accounts.
Let me know what you think

Sometimes a user's email credentials get hijacked and before we know
it 100,000 spams go out. This doesn't happen very often but when it
does it's a mess. Our mailserver gets blocked by major ISP and it
takes weeks to get the blocks lifted. So I was thinking - is there
any way to rate limit email accounts? For example, limit users to
sending no faster than one email every few seconds. There used to be
a patch for the old Bill's Qmail Toaster called 'spam throttle' that
could do this.
