Database Mail (Microsoft documentation) sends email messages, such as notifications or alerts, from a Microsoft SQL Server database by using a Simple Mail Transfer Protocol (SMTP) server. The Amazon Relational Database Service (Amazon RDS) for Microsoft SQL Server documentation provides instructions for using Amazon Simple Email Service (Amazon SES) as the SMTP server for Database Mail. For more information, see Using Database Mail on Amazon RDS for SQL Server. As an alternative configuration, this pattern explains how to configure Database Mail to send email from an Amazon RDS for SQL Server database (DB) instance by using an on-premises SMTP server as the mail server.
