A Zero Spam Mail System [Feedback Request]

[cabo at tzi.org (Carsten Bormann)]

Been there, done that (I wrote my own driver for the bisync card, so I didnâ??t have the latter problem, just had to tame a barely documented Motorola chip â??helpingâ?? with the already weird DLE handling).  Iâ??d still prefer doing that again over todayâ??s spam problem.

(There actually is a teachable lesson here, which is about getting rid of gateways.  But thatâ??s for another dayâ?¦)

Grü�e, Carsten
