Integrating Amazon SES with Postfix

To integrate ses-send-email.pl with Postfix

1. On your mail server, open the master.cf file. On many systems, this file resides in the /etc/postfix directory.

2. Configure a new mail transport: Add the following two lines to the master.cf file, modifying them to reflect your particular situation, and then save the file.

   aws-email  unix  -       n       n       -       -       pipe

     flags=R user=mailuser argv=/opt/third-party/amazon/ses-send-email.pl -r -k /opt/third-party/amazon/aws-credentials -e https://email.us-east-1.amazonaws.com -f ${sender} ${recipient}

   Note the following about these lines:

   • The flags line begins with at least one space.

   • The user parameter must specify a non-root user (i.e., a nonadministrative user). The user "mailuser" in the previous example is for illustrative purposes only.

   • The ses-send-email.pl script and the credentials file reside on your mail server in the /opt/third-party/amazon directory.

   • The endpoint for communicating with Amazon SES is always https://email.us-east-1.amazonaws.com.

3. Open the main.cf file in the same directory as master.cf.

4. Look for the default_transport line. If it exists, modify it as follows. If it doesn't exist, add the following line.

   default_transport = aws-email

5. When you are done, save the file.

6. Restart Postfix. At the command line, type the following command and press ENTER.

   sudo /etc/init.d/postfix restart

   	Note
   	This command may not be exactly the same on your particular server.
