In my experience, the most efficient way to decrease spam is to educate the users on how to use filtering. Simple mail filtering comes in most popular email clients these days, and after adding a few notorious spam domains as well as some of the most common phrases included in spam, it quickly drops to a point where it's hardly even annoying.
Personally, I've made it a habit to immediately add a specific persons email address, as well as the topic of their mail to my spam filter. At the present, I get 1, perhaps 2 spam mails per month, using only my internal spam filters to get rid of it.
I realize that this will not decrease the amount of bandwidth the spam mails consume, as the filtering is done on my machine, but I find it a relatively small price to pay in exchange for a minimal risk of non-spam mail not reaching me.
