Postfix In Open Relay....

Hello,

I believe that i had postfix in openrelay. I already had a spam run, i saw the logs and among my clients, i detected one doing spam, and them several unknown address sending from the server.

It is supposed to be a server that only accepts authentication method in order to let someone sending email. However, it is still sending spam… from unknown users… this is in did bad. :frowning:

Any help ? any sujestion^?

thanks
FIlipe

Hey Filipe,

What’s your smtpd_recipient_restrictions in main.cf look like? It ought to be:

permit_mynetworks permit_sasl_authenticated reject_unauth_destination
