To begin with the Amazon SES setup, you need to edit the exim configuration file very carefully and we suggest you take a backup of the exim configuration file prior to any edits. This way you can able to revert the file from the backup in case you get any configuration failure:

create a backup the file /etc/exim4/exim4.conf.template to get this done, use the command below:

cp /etc/exim4/exim4.conf.template /etc/exim4/exim4.conf.template-back

vi /etc/exim4/exim4.conf.template

Under ‘begin authenticators’ Please add the following lines:

ses_login:
driver = plaintext
public_name = LOGIN
client_send = : user : password

Under ‘begin routers’ Please add the following lines:

send_via_ses:
driver = manualroute
domains = ! +local_domains
transport = ses_smtp
route_list = * email-smtp.your-region.amazonaws.com;

Under ‘begin transports’ Please add the following lines:

ses_smtp:
driver = smtp
port = 587
hosts_require_auth = *
hosts_require_tls = *

It is mandatory to verify your domain before the steps above.
