does anyone know what spam scores hotmail, gmail, yahoo etc use to filter emails?
I use spamassassin to check, and they say upper limit for a clean email is 4.5 (they rate from 0 to 13+).. but i'm not sure 4.5 would get past hotmail junk filter.
0.0 - 4.5 - nice and clean, no problems except tiny ones below; no action required
4.6 - 7.0 - the strictest may object; clean up the easy-to-find issues (below)
7.1 - 10.0 - getting into dangerous territory; clean up any big issues and the easy-to-find smaller ones
10.1 - 13.0 likely over ISP limits; requires good review and cleaning up
13.1+ major problems; overhaul needed -- systematically clean, point by point and then re-test (this may require two or three checks).
