Hi All,
I am looking for a solution but don't find it to the net. Usually we
restrict user to do SMTP based on network. The users from permitted
network can use the mail server as SMTP server. Is there any way to
restrict with domain also. As I permit certain network, there is some
virus infected PC which use the SMTP server and send mail to various
email id; in all the cases source email address or domain is not my
domain. What I want is if my domain name is example.com, my SMTP
server will only allow to send mail if the mail is sent from the
domain example.com. Is there any way to do it with any version of
postfix.
