Oh, I should have mentioned my experience with one pay service. My
/dev/boss was formerly affiliated with MailDeflector. Some of their 
features sound good, but oh boy, there's something seriously wrong in 
the code.

They have a bot which takes contributions from any and all subscribers. 
I've not see the code, but judging from some of the listed IP's (in 
many unassigned and reserved netblocks) I think this bot must not be 
smart enough to determine which Received: header is valid and which is 
a fake.

MailDeflector is useless, avoid. Worse than useless: once we switched 
away from it, false positives became very rare. The few I've seen since 
then were blocked by virtue of misconfigured mailers or DNS. They call, 
we whitelist, customer is accepting of this level of false positives 
and happy with the reduction in spam.
