Issue

Emails are not received in AWS SES SMTP server when VPC endpoint is configured.

Environment

  • Tableau Server 2021.2.0
  •  AWS SES SMTP server with VPC endpoint

Resolution

Verify the inbound rule (firewall rule) in the SMTP security group that is configured for VPC endpoint in AWS allows the subnet range of Tableau Server nodes.

Troubleshooting steps:
  1. Confirm the email is successfully sent when VPC endpoint is not configured (and inbound rule for SMTP port in Tableau role is applied instead). The result indicates whether VPC configuration can be the possible cause of the issue. 
  2. Follow AWS documentation to send test email from each Tableau node (especially the nodes with backgrounder that performs the task) to smtp server.

Cause

In the inbound rule of SMTP security group only the IP range of the initial node was allowed instead of all Tableau Server nodes.
