Re: unsecure smtp 25

Find lines below in /etc/postfix/main.cf, then uncomment the last 4 lines:

#
# Enable SASL authentication on port 25 and force TLS-encrypted SASL authentication.
# WARNING: NOT RECOMMENDED to enable smtp auth on port 25, all end users should
#          be forced to submit email through port 587 instead.
#
#smtpd_sasl_auth_enable = yes
#smtpd_tls_auth_only = yes
#smtpd_sasl_security_options = noanonymous
#smtpd_tls_security_level = may
