Ok, <bump> for 0spam!!
Been usin' it for a few weeks now, and its pretty good.
Much better than Spamihlator, or other spam filters than work AFTER downloading email.
No issues about spam frmm 0spam either, yet.

Pretty neat, really, as it's free for 2 emai addresses.
Anybody else wanna try it and tell me what they reckon?
Cheers
Mick
