relayhost = [email-smtp.eu-west-1.amazonaws.com]:587
smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = static:USERNAME:PASSWORD
smtp_use_tls = yes
smtp_tls_security_level = encrypt
smtp_tls_note_starttls_offer = yes
# end AWS settings

Save your changes and exit.

Restart the postfix server.
