Alrighty I'm setting up a new postfix mail server and I had a question about spam. I've read that using RBLs and spamassassin can really slow down the mail server so I'm probably going to start out with just one. If one method can block a lot of the spam then I'll be set. If a lot of spam still gets through then I'll probably use both.

So which should i use, a blackhole list like spamhaus, or spamassassin?

Also for those who recommend spamassassin, if you have any good links that explain how to configure spamassassin with postfix id appreciate it. Thanks.

You're not supposed to bump a thread until at least 24 hours passes; doing so is a good way to get ignored (and get spanked by the mods)

well, since you replied with that, and I now get to reply to your reply, I get two more free bumps...

Thanks!

Now back to my thread:

I think Im going to setup the blackhole list now, and if it does a good job at blocking a majority of our spam, and I dont get any reports of email not being received I'll stick to that. If the blackhole list doesnt work I'll setup spamassassin and see how the two together effect my email performance. If using both is too taxing I'll eliminate the blackhole list and stick with sa.

Spamassassin on my server blocks about 99% of spam. Maybe 98% to be fair, but out of 100's of spam emails per day it does a decent job.

That's after lot of tweaking though. By default it practically lets everything through, the default rules SUCK, but fear not, as you can download some, and by enabling bayes, you should increase it's accuracy.

Take a look at how to use spamd/spamc combination which is much more efficient then the "normal" default way of using it.

Good luck killing spam! I have a passion for it myself.

And here's another "free bump" for you, this time from
a mod. And next time you bump before 24 hours have
passed I'll either close you thread myself or have it
closed by another mod. You were in a clear violation
of the rules you agreed to.

Just to make it clear.... the forum software auto-bumps posts with 0 replies.....

Your always better off leaving it at 0 replies then bumping it as it will get bumped automatically and it will stay on the 0 reply list that so many users check for questions to answer.
