It looks as though the problem with outlook express has been resolved now. On my pc the antispam plugin would only show up in outlook express after a re-boot of my pc, then after about 10mins it would dissapear altogether. Seems to be ok now though as I have had my pc on for 4 days and each time I check my emails in o/express, it's still there.
glad about that as i didn't really like using ms-outlook in ms-office, not as usr friendly and much slower than o/express
