Integrating Amazon SES with Sendmail

To integrate ses-send-email.pl with Sendmail

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

2. Configure a new mailer: Add the following line to the file, modifying it to reflect your particular situation:

   Maws-email,         P=/opt/third-party/amazon/ses-send-email.pl, F=mDFMuXn, U=mailuser, S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP, A=ses-send-email.pl -r -k /opt/third-party/amazon/aws-credentials -e   https://email.us-east-1.amazonaws.com   -f $f $u

   Note the following about this example:

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

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

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

   You should modify these parameters as appropriate.

3. Verify that the mailertable feature is enabled. Look for the following line:

   FEATURE(`mailertable')dnl

   If this line does not exist, you will need to add it.

4. Save sendmail.cf.

5. Open the mailertable file. On many systems, this file resides in the /etc/mail directory. If the file does not exist, create it.

6. Add the following line to send all email using the aws-email mailer:

   .<TAB>aws-email:%0

   	Note
   	Replace <TAB> with an actual TAB character.

7. Build the mailertable database.

   makemap hash /etc/mail/mailertable < /etc/mail/mailertable

8. To verify your configuration, generate a deliverability report:

   sendmail -bv user@example.com

9. In this report, look for the following output:

   user@example.com... deliverable: mailer awsemail, host example.com, user user@example.com

10. Restart Sendmail. At the command line, type the following command and press ENTER.

    sudo /etc/init.d/sendmail restart
