The rules have updated more recently, though I couldn't say how 
regularly offhand. Updating the rules is not necessarily tied to 
updating the package, and has proven beneficial in the past. Worth 
looking into.

For home I use SA, Spamhaus' Zen RBL, and a greylisting milter with 
sendmail as the underlying MTA. Works pretty darned well.

For work, with users well into six figures, we've been using Proofpoint 
for years and are quite happy with them. They now offer filtering in the 
cloud, similar (but IMHO better) to what Postini used to do. I'd have no 
hesitation recommending their services, on-prem or off-, if you have the 
budget and need the support.
