email, spam, filters

It depends what you're blocking on. You can stop a substantial amount of spam just by blocking open relay servers with a list like ORDB and have virtually no false positives (people who send legit mail tend to fix their open relays pretty quickly; the ones which stick around are run by people who don't use them anyway).

There's also a fantastic list (~3MB usually) at http://basic.wirehub.nl/spamlist-extended.txt full of sender email addresses to block. We download that once a day at work and get quite a few kills from it. Only issue I've had is that they block mass-mailing places like DoubleClick Dartmail and Microsoft bCentral, and believe it or not a few legit companies use those too. Still not much whitelisting involved.

For the more agressive approach there are lists like SPEWS and SpamCop. That sort of list is high in collateral damage. So if you don't want to block legit mail, don't use them.

I use a program called "I HATE SPAM" by Sunbelt Software.

Free evaluation here:

System is easy to configure and catches about 95% of the spam. I have been using it for months and am very happy with it.

Ok, clip my two cents here as well.

As far as a recommendation for POPmail software?
Depends.
Personally I use OE because of the availablility of multiple accounts, (15) within one package which correctly uses the assoociated sntp for the account with which you're sending out on.
7 Pop/sntp accounts at one server
2 pop only accounts
3 hotmails
3 yahoo fetchers.
My sntp server requires each sender to be authorized for sending, but should I chose to do so, I can reply via the various accounts through that server with the correct return address.
