[wplug-internet] Spam filters

[Justin Smith]

Hey guys,

We use Pair Networks for our email at work. The boss had me call them up 
today because their spam filters weren't cutting it, and the rep I spoke 
with walked me through setting up DNSBLs. They were so effective that it 
was almost like flipping and "off" switch. I haven't received a single junk 
email since then.

I was so impressed that I thought I'd give it a shot on our WPLUG mail 
server. I added three DNSBLs: Spamhaus Zen, Spamcop, and another one 
whose name escapes me because I'm on the verge of falling asleep.

There were comments in the /etc/postfix/main.cf file that suggest that 
someone tried to use one of Spamhaus's lists at one time and found that 
it ineffective. The difference here is that I'm using a much more 
comprehensive list from Spamhaus and I placed the restrictions in 
/recipient/ smtpd filtering rather than client smtpd filtering. That, 
supposedly, is what makes the difference.

Let's see if it get as many junk messages on the mailing lists now.
