I gotten a VPS recently and I wanted to host my own websites and with that, the ability to send and receive mail.

I set up my mail server according to this guide:

And it worked: I can access the SMTP with STARTTSL and IMAP server with authentication, all on standard port.

But now my Postfix turned into a spam server (currently it has 200+ mails queued up) and I was forced to turn it down. Also it always got all the MySQL connections, and websites couldn't connect to it.

How can I fix my Postfix?

seems like my server wasn't compromised it just my settings allowed anyone to connect to it, and use it without authentication.

in my I changed the mynetworks = [::/0] to mynetworks = [::ffff:]/104 [::1]/128 and removed the permit from smtpd_client_restrictions

after i cleared the queue and started the server none of the problems i experienced seems to appear again.
