Integrating Amazon SES with Sendmail - Amazon Simple Email Service

Integrating Amazon SES with Sendmail - Amazon Simple Email Service:

Sendmail was released in the early 1980s, and has been continuously improved ever since. It is a very flexible and configurable MTA, and it has a large installed base.

For information about Sendmail, go to http://www.sendmail.com/sm/open_source/.

To configure integration using STARTTLS

1. Edit the /etc/mail/authinfo file. If the file does not exist, create it. Add the following lines to the file, replacing USERNAME and PASSWORD with your SMTP user name and password.

   AuthInfo:email-smtp.us-east-1.amazonaws.com "U:root" "I:USERNAME" "P:PASSWORD" "M:LOGIN"
   AuthInfo:ses-smtp-prod-335357831.us-east-1.elb.amazonaws.com "U:root" "I:USERNAME" "P:PASSWORD" "M:LOGIN"
                       

2. Save the authinfo file.
3. At a command prompt, issue the following command to generate the Sendmail configuration file:
   makemap hash authinfo < authinfo
4. Edit the /etc/mail/sendmail.mc file. If the file does not exist, you can obtain it by installing the sendmail.cf package on your system. In the sendmail.mc file, add the following lines:

   define(`SMART_HOST', `email-smtp.us-east-1.amazonaws.com')dnl
   define(`RELAY_MAILER_ARGS', `TCP $h 25')dnl
   define(`confAUTH_MECHANISMS', `LOGIN PLAIN')dnl
   FEATURE(`authinfo', `hash -o /etc/mail/authinfo.db')dnl
                       

   	Note
   	Be sure that relaying is allowed for email-smtp.us-east-1.amazonaws.com in the /etc/mail/access file.

5. Save the sendmail.mc file.
6. Issue the following command:
   m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
   

   if you get following error
   m4:/etc/mail/sendmail.mc:10: cannot open `/usr/share/sendmail-cf/m4/cf.m4': No such file or directory
   then
   yum install sendmail-cf
