Hi
I've got a Postfix 2.6.6 mail server on CentOS where I want to accept
emails only for members of a certain unix group (e.g. group mailuser)
and reject everyone else.
I believe it should be done with local_recipient_maps but I can't figure
out how to make it check the unix user membership..
The default setting "local_recipient_maps = unix:passwd.byname
$alias_maps" obviously accepts emails to all existing user accounts. How
can I restrict it only to members of the specific group?
Alternatively I've got dovecot on the box as well - perhaps I could
query dovecot whether the user is valid or not from
local_recipient_maps? But how?
Thanks for any hints
Michael
