Blocking all of digitalocean.com?

I guess that’s fine if you don’t mind having mostly false negatives.  You’d be better off teaching your antispam system to treat the netblock with more suspicion.  The spam I got had enough other rules that it was already in the “maybe spam” score, I bet if I created a spamassasin rule for it, it’d push it over the top.
