I know this question is a year old but why use the script when Postfix handles relaying through SES just fine using SMTP.
You can either setup your
relayhost if the only email being sent is from a verified sender or verified domain or you can use
sender_dependent_relayhost_maps to relay only those domains and senders verified.
In either case you would start by setting up the SASL password for SMTP AUTH. I use
/etc/postfix/sasl_password and it should follow the format of:
Update to use the SMTP host from your AWS SES Console and the appropriate SES SMTP user credentials. Next you need to configure the SMTP SASL client settings in
/etc/postfix/main.cf by adding the following:
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_password
smtp_sasl_mechanism_filter = login
postmap /etc/postfix/sasl_password and that is all set. Now you have to decide if you're relaying everything or just verified senders/domains. If relaying everything then simply add the following to your
relayhost = email-smtp.us-east-1.amazonaws.com
On the other hand if you only want to send verified senders/domains then add the following to your
sender_dependent_relayhost_maps = hash:/etc/postfix/relayhost_maps
/etc/postfix/relayhost_maps add your verified senders/domains following the format of:
Run that file through
postmap /etc/postfix/relayhost_maps and do a
postfix reload and you should be sending emails through SES.
