Bayesian type filters do indeed a good job filtering for spam. But they do
nothing to stop spam and they don't reduce the corresponding bandwidth use.
This is specifically a problem for users using a slow modem.

Double opt-in is the norm in these times...

There are many ways a script can be exploited. I suggest that you read about
the vulnarabilities in the famous FormMail script
(www.monkeys.com/anti-spam/formmail-advisory.pdf) so you can decide whether
one of these problems apply to your script.
