I tried to follow the wiki article RestrictPostfixRecipients - Zimbra :: Wiki
My goal is to limit sender to a particular recipient ( recipient is distribution list )
when I set
smtpd_recipient_restrictions = check_recipient_access hash:/opt/zimbra/postfix/conf/protected_recipients, (rest of line here)
in main.cf, as article say , this option is resetted after "postfix reload"
How can I set up the smtpd_recipient_restrictions option in portfic main.cf file ?
Reading manual at chapter 5 I found information about smtp restriction
"In the administration console, you can enable restrictions so that messages are not accepted by Postfix when non-standard or ... "
but I did not found this option in admin console
Please can someone show me where I can change this option ?
Thanks a lot
