Set Postfix to block fake emails
Posted on 2008-10-22
I just want to set postfix to block fake emails that can just type:
MAIL FROM: email@example.com
RCPT TO: firstname.lastname@example.org
Of curse IP of sender is not even related with google's IP or their MX
I blocked almost all unwanted functionality in postfix, but I cant find proper information in documentation. I tried varies settings but all of them fails to prevent sending mail to mine server that way. I assume that this is a simple task, and you - experts - will get with this in 2 minutes... So can you help me ?
