SMTP

Sending mail is a common feature for Grafana. After a large number of user practice feedback, only one way is recommended, that is, using the third-party STMP service to send the email.

Do not try to install Sendmail or other Mail server software on your Cloud Server for sending mail, because it is very difficulty in maintenance.

Follow is the sample using SendGrid's SMTP Service to configure sending mail for Grafana:

1. Log in SendGrid console, prepare your SMTP settings like the follow sample

   SMTP host: smtp.sendgrid.net
   SMTP port: 25 or 587 for unencrypted/TLS email, 465 for SSL-encrypted email
   SMTP Authentication: must be checked
   SMTP Encryption: must SSL
   SMTP username: websoft9smpt
   SMTP password: #fdfwwBJ8f    
   

2. Edit the SMTP segment part in Grafana configuration file and fill in your SMTP items

   #################################### SMTP / Emailing #####################
   [smtp]
   enabled = false
   host = localhost:25
   user =
   # If the password contains # or ; you have to wrap it with triple quotes. Ex """#password;"""
   password =
   cert_file =
   key_file =
   skip_verify = false
   from_address = admin@grafana.localhost
   from_name = Grafana
   ehlo_identity =
   
   [emails]
   welcome_email_on_sign_up = false
   templates_pattern = emails/*.html
   

3. Restart Service

   sudo systemctl restart grafana-server
   

4. Log in Grafana Console, Open: Alerting > Alert Rules, create new Notification Channel and select the type with Email
5. Click the Test Connection, you can get the feedback "no errors were..." if SMTP is useful
