Bounce non-spam messages

[Ramon Acedo]

Hello,

from time to time users ask if is there the possibility of bouncing
emails from a particular sender. This sender can be a legitimate sender
for the system (but not for the user asking for his messages to be
dropped).

Is there any way of managing this in MS? I'm trying to do it with
Sendmail feature "delay_checks hater" and "access_db" but it isn't
work as I expect.

AFAIK MS doesn't implement this feature but I'm wondering if one could
play with the bounce of the "Enable Spam Bounce" rules. I actually think
it wouldn't be very complicated because the current rules allow 2
condition rules (i.e "From: a at b.c and To: myuser at mydoma.in bounce")

Thanks,

Ramon
