Virtualmin: Enable Postfix SSL for SMTP


Follow the steps to enable the Postfix SSL for SMTP in the Virtualmin server:

1. Login to Virtualmin control panel. https://xx.xx.xx.xx:1000

2. Click Edit Virtual Server. Go into Enabled Features and check “ Setup SSL website too ? ”, then hit save


If the web server is nginx then the option will be ” Nginx SSL website “


3. Edit /etc/postfix/ Find these lines and uncomment them:

# smtps inet n - n - - smtpd

# -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


4. Restart SSL AUTH daemon 

# /etc/init.d/saslauthd restart


5. Server Configuration -> Manage SSL Certificate and Click the button “Copy to Postfix” at the bottom. That’ll setup Postfix with that new SSL cert you just created.


6. Restart mail server

# /etc/init.d/postfix restart
