if the world was so simple that we would all use gmail accounts.. guess i would shoot myself
if you´re running your own servers, britts-vajayjay - i guess there is no help that i knew of! a spamfilter for ANY mailprovider (myself included) would be a big hit, especially if it would recognize spamsignatures / X-Headers from tools like SpamAssassin.
If you know of any - please let me know, i share the same problem as you do with over 1.500 spams coming in a day. having a flatrate i really don´t care downloading them, but SORTING them out is a real PITA on my E61.
