Configure SMTP settings for email notifications
Deep Security Manager can send emails to users when selected alerts are triggered (see Configure alerts). Before setting up the email notifications, you need to allow Deep Security Manager access to a simple mail transfer protocol (SMTP) mail server:
  1. Go to Administration > System Settings > SMTP.
  2. Type the IP address or hostname of your SMTP email server. Include the port number if different from the default port number. AWS throttles (rate limits) email on the Internet Assigned Numbers Authority (IANA) standard port number for SMTP: Port 25. If you use AWS Marketplace, you may have faster alerts if you instead use SMTP over StartTLS (Start Transport Layer Security, a secure type of SMTP). For more information, see https://docs.aws.amazon.com/ses/latest/DeveloperGuide/smtp-connect.html.
  3. Use the From field to enter the email address from which the emails should be sent. If you are using Amazon Simple Email Service (SES), the sender email address must be verified. To learn how to verify your email address in Amazon SES and view a list of addresses you have already verified, see https://docs.aws.amazon.com/ses/latest/DeveloperGuide/verify-email-addresses.html.
  4. Optionally, type a bounce address to which delivery status notifications (DSN) should be sent if the alert emails cannot be delivered to one or more users.
  5. If your SMTP mail server requires outgoing authentication, type the user name and password credentials.
  6. Select STARTTLS if your SMTP server supports the protocol. Deep Security Manager FIPS mode supports StarTTLS in Deep Security Manager 20 LTS Update 2022-03-22 and later. See FIPS 140 support.
  7. After entering the necessary information, click Test SMTP Settings to test the connection.
