hello, in our postfix setup we use virtual_alias_maps to build some simple mailing-/distribution lists. now we want to reject every mail to a list where the sender is not a member of the list.
example: virtual_alias_maps [email protected] [email protected] [email protected] [email protected] [email protected] [email protected] [email protected] [email protected] [email protected] is allowed to send to [email protected] but not to send to [email protected] [email protected] is allowed to send to [email protected] but not to send to [email protected] [email protected] is allowed to send to [email protected] but not to [email protected] to accomplish this i found http://www.postfix.org/RESTRICTION_CLASS_README.html#internal and it seems to work. but im not sure how this will scale with a greater amount of lists/members and if it would be a better decision to use some policy daemon to do this stuff. any recommendations? thanks for you help! heiko
