After Login to Zabbix Admin, we need to goto below location:
Administration > Media types > Email
Below are details of the fields:
Type: Should be Selected the option ‘Email’.
SMTP server: 127.0.0.1 (127.0.0.1 should be used if we are already running email server eg: Postfix on Zabbix server, otherwise we need to enter the relevant IP of our email server)
SMTP server port: 25 (Mostly this is the port)
SMTP helo: Optional
SMTP email: Email address which we want to show to recipient
Connection security: None
Finally we need to update and wait for the emails to be delivered.
Please share your comments below in case any issue appears in setup.
