Re: Multiple port on smtp tls

In /etc/postfix/master.cf, copy submission settings and paste in same file, but replace 'submission' by a port number.

999 inet n       -       n       -       -       smtpd
  -o syslog_name=postfix/999
  -o smtpd_tls_security_level=encrypt
  -o smtpd_sasl_auth_enable=yes
  -o smtpd_client_restrictions=permit_sasl_authenticated,reject
  -o content_filter=smtp-amavis:[127.0.0.1]:10026
