Integrating with Amazon SES
If you're self hosting, here is the method I used to route emails through Amazon's SES service.
For me, when hosting on AWS the public IP is widely blacklisted for abuse. If you have an SES account, you are whitelisted, use TLS, and amazon creates the DKIM records.
First, I modify the postfix inet protocols to only route via IPv4: in /etc/postfix/main.cf, change inet_protocols = ipv4
Amazon Simple Email Service Console:
First, verify your domain with SES, and check off "Generate DKIM Records".
I use Route53, so pressing the Use Route53 button will automatically generate my DNS values. If you do not use Route53, you will have to create them on your DNS provider.
If you do choose route53, this is what generating the record sets looks like
Now, in SES we need to generate SMTP Credentials to use. Go to the SMTP settings tab, and create credentails. Also note your server name, port, etc.
Now on your server, run the following (Updating the SMTP DNS address to match what you see in the SMTP settings tab of SES)
sudo postconf -e "relayhost = [email-smtp.us-east-1.amazonaws.com]:587" \
"smtp_sasl_auth_enable = yes" \
"smtp_sasl_security_options = noanonymous" \
"smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd" \
"smtp_use_tls = yes" \
"smtp_tls_security_level = may" \
"smtp_tls_note_starttls_offer = yes"
Now let's create /etc/postfix/sasl_passwd and inside put your SMTP Setting values;
[email-smtp.us-east-1.amazonaws.com]:587 SMTPUSERNAME:SMTPPASSWORD
Create a hashmap with sudo postmap hash:/etc/postfix/sasl_passwd
Secure the files (optional but recommended)
sudo chown root:root /etc/postfix/sasl_passwd /etc/postfix/sasl_passwd.db
sudo chmod 0600 /etc/postfix/sasl_passwd /etc/postfix/sasl_passwd.db
For Ubuntu, we point postfix to the CA Certs;
sudo postconf -e 'smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt'
Also make sure that Postfix is able to authenticate successfully by installing the SASL package:
sudo apt install libsasl2-modules
Then restart postfix
sudo systemctl restart postfix
and you should see the mail in /var/log/mail.log and in your alias emails routed through Amazons servers!
