We must first allow postfix to listen on port SMTPS aka port 465


1. Edit your /etc/postfix/master.conf and make sure you have the following lines uncommented :
Code:
smtps inet 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 milter_macro_daemon_name=ORIGINATING
2. Restart postfix :
#service postfix restart
3. Restart dovecot :
#service dovecot restart
4. Create / modify a new account on your email client and use the following settings for SMTP server :
Port : 465
