Question Postfix open and configure smtpd

[OverWolf]

Hi,

after I read this KB : How to use another port for SMTP connection if 25 port is blocked by ISP I have had some doubts.
- In master.cf shouldn't remove # from "submission inet n – n – – smtpd" ?
- Should I put # in front of "smtp inet n - n - - smtpd "?
- is it recommended to use SSL (465) and change to "smtps inet n – n – – smtpd "?

My mod like

smtpd_tls_security_level = may
smtpd_use_tls = yes
smtp_tls_security_level = encrypt
smtp_use_tls = yes
smtp_tls_mandatory_protocols = TLSv1 TLSv1.1 TLSv1.2
smtp_tls_protocols = TLSv1 TLSv1.1 TLSv1.2
smtpd_tls_dh1024_param_file = /etc/dhparam/dhparam2048.pem
smtp_tls_exclude_ciphers = aNULL, eNULL,
etc.

are set in main.cf. Is this ok ?

Thank you
