Hi All
I have a question regarding postfix restrictions.
Is there a way for Postfix to enforce some kind of policy so that all
the outgoing (allowed) mails be " @business.com" and all the others be
rejected.
Of course this policy should be enforced only to the outgoing emails
not in the incoming.
- if mail comes from mynetworks, require that the sender address is
*...@example.com. you can do this with a restriction class based on
check_client_access.
Thanks for the reply
I did this
mynetworks = cidr:/etc/postfix/inside_network
smtpd_restriction_classes=
from_inside_network
from_inside_network =
check_client_access cidr:/etc/postfix/inside_network
smtpd_recipient_restrictions =
check_sender_access hash:/etc/postfix/sending-domains,
reject_unauth_destination
/etc/postfix/inside_network
192.168.2.0/24 OK
127.0.0.0/8 OK
/etc/postfix/sending-domains
business.gr from_inside_network
So I did a logical AND -> all clients form my network have the relay
privilege and moreover they can send e-mails only from business.gr
(hopefully)
I need to test it on a production server.
