i guess a list manager is overkill for our setup. we just export the alias maps from a db and only need the additional feature to block mails to a list from an "unknown" sender. it looks like we can redirect mail via the policy interface in postfix. is it okay to use a policy daemon for redirection or are there any drawbacks? anyone using such a setup?
