I'm suprised that people haven't done a better job at building better
SMTP filters.. Unfortunately what I wrote was on company time, so I can't
release it (grrrrrr), but I definately have the flexability to do stuff
like this (indeed, this isn't the first time MSN mail was blocked, and
I was not affected by Vixie's decisions):
[...]
I'm not sure how easy/hard it would be to maintain *sendmail* that way..
However,
I have sendmail configured to do/not do various filtering (RBL, ...)
on a per end-user basis. it works well, and keeps most people happy.
was fairly easy to setup. a bit harder than brain surgery, but not much...
