Probably a simple question: I want a distribution list on my domain. But, to
prevent spammers to use it, I want some security (example the ip-number I
sent the mail from). So what I like to do in pseudocode:
if sender's ip = 18.104.22.168
then forward this mail to user1, user2, user3 etc.
dump it in a file called ubusers
Does anyone know how to do this in procmail?
