SpamAssassin as a for-profit forwarding or proxying service?

[Gordon Mohr]

Someone should offer the forwarding-filter Dan seeks as
a paid service. Lots of people would want an easy, turnkey
spam block. I'd pay a few bucks a month for one.

Proxying the mail-get protocols might work better for
many users than setting up a secret "inner" account
that only gets the good mail. 

Brightmail used to have a nifty POP proxy service, where 
you'd go through their servers, to your real POP server(s), 
to have their spam filtering applied before any messages 
got to your local display/folders.

Sadly, it was buggy at "leaving messages on server", so I 
only tried it briefly. Since then, Brightmail's services for 
individuals seem to have disappeared.

The approach seems sound, though, and would work really
well for people who don't want to juggle new "hidden"
accounts or whose local mail clients can't sort-by-header.

I'd want all the filtered mail to go into a "purgatory"
area. I'd get an update -- say once-a-week -- informing me 
how many messages are in purgatory, with a link to a web
interface for browsing them.

At that interface, I'd be able to quickly scan over many
messages for non-spam, and have single-click options for
releasing messages from purgatory or permanently 
whitelisting their origin.
