I have a complicated settings, and I hope I can have some advice.
I setup the access rule to block the outsider sending mails to the
internal mail group.
This is what I did.
/etc/postfix/main.cf
.....
check_client_access hash:/etc/postfix/access
.....
.....
/etc/postfix/access
[email protected] mynetworks,reject
I need to allow [email protected] to send mail to [email protected] from outsider of
mynetworks.
[email protected] is one of the recipient in the [email protected] mail group.
Thanks,
Andrew
