I'm the system admin (though I'm not great at it). I have a problem with spam. Hundreds of spam messages are posted to my lists each week. They're non-subscribers so they don't go to the lists, but they *do* go to me, the list owner which floods my inbox.

I'm looking at the page on how to use SpamAssassin:

https://wiki.list.org/DOC/4.23%20How%20do%20I%20use%20SpamAssassin%20with%20...

Is that the best way to do what I need? If so, what's the best method to use in my case? My system: Mailman 2.1.20 Apache2 / 2.4.18 Postfix 3.1.0 Ubuntu 16.04.1 LTS

With Postfix, you should activate the built-in SPAM control, "postscreen".

The details on how to use it are in POSTCSCREEN_README when you install from source, I don't where/if Ubuntu puts it, or if they build it for their distro, but it just works. "man postscreen" should get you started.

I have it checking spamhaus.org, spamcop.net, and barracudacentral.org for blacklisting.

I sometimes add IP ranges to "/etc/postfix/postscreeen_access.cidr", (they've mainly been from Brazil, Korea, and China), when I notice a new source that the blacklists haven't yet found, blocking out vast swathes of the internet doesn't trouble me.
