After postfix and dovecot were installed, there are 4 ports open by default.
port 587 port 25 port 993 port 143 So I have improved them by implementing: 1. close public port 143 2. disable sasl auth on port 25 3. force smtp client to login using tls only on port 587 do you think there is any stuff I am missing? Thanks.
I'm updating the Postfix documentation that "smtpd_tls_security_level = encrypt" will reject all plaintext commands except HELO, EHLO, XCLIENT, STARTTLS, NOOP, QUIT, and HELP.
