I have a distributionlist firstname.lastname@example.org. This address is only for internal use.
So I want to reject all incoming mail, From: any To:email@example.com.
Is this possible ?
I have checked some postfix-options such as:
smtpd_sender_restrictions, but this option checks the FROM:
smtpd_recipient_restrictions, this option is for outgoing mails
I am using Zimbra 5.0.11.
