My point was that there's no real *need* to distinguish between a legitimate
user sending 20 emails and an 0wned box sending 20 emails, as the distinction
is "legitimate 20 emails" versus "0wned 20K emails".

If I were to only give my users 20 outbound connections/day, there wouldn't be
a per-mail-server issue. Whether I can make such a policy stick is another
question entirely.
