An alert configuration file must be created to specify where your SMTP server resides. Here is the template of the alertconfig.yaml file:
email:
  receivers:
    - receiver@example.com
  sender: sender@example.com
  server:
    host: smtp.example.com
    port: 25
    username:
    password:
Modify this file by:
- 
Updating the hostfield to reflect the host of the SMTP server.
- 
Updating the portto reflect the port that your SMTP server is listening on. This port must be open and available.
- 
Updating sendersandreceiversdetails to reflect where the email will be sent to and received from.
- 
Updating the usernameandpasswordif needed.
The following example file shows a configuration of an SMTP server running on an EC2 instance, sending an email to a singlestore.user Gmail user. You may add multiple recipients to the receiver list.
email:
  receivers:
    - singlestore.user@gmail.com
  sender: ec2-user@ip-172-31-77-34.ec2.internal
  server:
    host: ip-172-30-77-34.ec2.internal
    port: 25
    username: 
    password:
