That spam protection won't help you if a spammer uses a dictionary list to
send email. The most common type of spam right now is a dictionary attack on
domains you host, not relaying to hosts you don't.
meaning they will send hundreds of thousands of messages addressed like this
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
And so on. One host I know routinely gets upwards of a million emails a day
addressed like this. This is the greatest single threat to ISP's today. Most
servers can't handle this.

Interesting. I'll see if we can contact Sylvain and get something done
about that if it really is a confirmed spam hole.
Our spam protection is basically not allowing any messages originating
outside our network to be delivered to any domain not hosted on that VOPMail
machine. Since this is configured by IP address, the "from" address really
isn't an issue in our configuration.
