Hi,
     We are having trouble in configuring 465 port on all mail clients . We have enabled the smtps as below in the
     master.cf
465     inet  n       -       n       -       -       smtpd
  -o syslog_name=postfix/smtps
  -o smtpd_tls_wrappermode=yes
  -o smtpd_sasl_auth_enable=yes
  -o smtpd_client_restrictions=permit_sasl_authenticated,reject
  -o content_filter=smtp-amavis:[127.0.0.1]:10026

We are able to telnet 465  from localhost. Ther is no iptables rules set . But the port 465  shows as closed from outside network. Please help to resolve the issue ASAP

Thanks in advance
