You have to get a domain and put in front. You need to be able to set your own mx records so you can do your scanning of messages on these mx servers. This is how most of these 'anti spam' providers work. > > In my own testing of this, my gmail Spam folder varies between 1500 and > 5000 messages at any given time.

So I personally find such a plumbing to be useful. You have to also check if not a lot of spamassassin knowledge comes from external sources like dnsbl and dnsuribl. If you would scale your service, you need to start paying for these. Register a new domain notgmail.com, setup your own mx forward, scan and forward to gmail. Afaik you should be able to configure gmail to use notgmail.com as outgoing email address. > What I have is a plumbing that does the message manipulation and a bunch > of other things which are not pertinent.

If a user drags it to a specific folder, it is unmarked and the unmarked message is put back in inbox and the sender is whitelisted for ever. > honestly say the devil is in the details, but the good news is that part > now works well.

Lots of companies are interested in better archiving their documents with their correspondence. Most of those services hook into your mailbox to do all kinds of management tagging, searching etc. That has target audience willing to pay for such service.
