Securing an Email Server
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256
I am running an email server Postfix/Dovecot. I had solved the problem
with securing the IMAP connection (ie: Requiring an SSL/TLS connection
before authenticating) Now I need to set the server to require an
SSL/LTS connection and to authenticate to the server before being able
to send an outgoing email. (

configure the pop3 connection to require an SSL/TLS connection to
authenticate, I am currently doing that with the system firewall, but I
am assuuming that this is not best practice.
