I want to apply per-hour mail limits using policyd in CentOS. I want to restrict each email account on the server to only be able to send out a maximum of 50 mails per hour. How can I do that?
I am managing a mail server. The mail server is running with multiple domains configured. The problem is authenticated user can use any sender email ID and I need to prevent it. How can I do that?
Example: a sender with email anything@example.com is sending mail with sender email address as anything@yahoo.com
I need to prevent that.
