Best practice (and current) anti-spam practices in Plesk

[exceedis]

I have Plesk 12 (haven't upgraded to 12.5 yet) on 2008 R2. I want to know if there are some obvious things to do to reduce spam that I haven't done yet. Currently I have SpamAssassin enabled and use three different DNS blacklists. MailEnable seams to complain if I use four or more. I chose these based on some research online as to popularity and their approach. I haven't done anything else. I'm not looking to achieve Gmail level cleanliness of the inbox, but I'd like to get as close as possible with the free approach. I only host for family and a few small clients as a value-add service to other things I do. What practices do you use?

First of all I'd suggest you try to use all available in Plesk antispam tools - http://docs.plesk.com/en-US/12.5/administrator-guide/mail/antispam-tools.59431/ and choose most effective for you.

Thanks IgorG. I have read that document. I also employ DKIM and SPF DNS settings for my own domains, but haven't enabled filtering for inbound email. These methods require the cooperation of the other end of the chain. Research hasn't given me the confidence to start denying inbound mail yet. But I'd love to hear the results of people who have.
