 By default, Icinga supports email notifications, but we need to configure an email server on the Icinga node as it will be using the Linux mail utilities for sending the mails.
 
+During the initial installation, we installed `postfix`. Now we need to add google credentials to it so that your server can send mails using Google.
+
+Edit `/etc/postfix/main.cf`
+
+Change following. ( DO NOT copy paste these in to the end of the file )
+
+{{{
+
+# TLS parameters
+smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
+smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
+smtpd_tls_security_level=may
+
+smtp_tls_CApath=/etc/ssl/certs
+smtp_tls_security_level=may
+smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
+
+relayhost = [smtp.gmail.com]:587
+smtp_use_tls = yes
+smtp_sasl_auth_enable = yes
+smtp_sasl_security_options =
+smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
+smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt
+
+}}}
+
+Create `/etc/postfix/sasl_passwd` with your Google username and password
+
+{{{
+[smtp.gmail.com]:587 thilinapathiedulk@gmail.com:MyPassw)<#
+}}}
+
+where `MyPassw)<#` would be my password for google. On google you have to make sure, Less Secure Apps are enabled.
+
+now restart postfix
+
+`systemctl restart postfix`
+
+Test mail transport by `mail -s "Hello World" youremail@yourdomain.tld`
