Hi guys,

I followed this guide at Linode to have a postfix + dovecot and mysql configuration
https://www.linode.com/docs/email/postf ... -and-mysql

It all worked.

But, I have this requirement where using the same setup. I need to send all postfix emails to Amazon SES. I am lost right now on how to combine Amazon SES with this setup, as some might conflict with the existing config.

Code:
Amazon SES

smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_use_tls = yes
smtp_tls_security_level = encrypt
smtp_tls_note_starttls_offer = yes


Code:
postconf -n

Looks like you are on the right track in setting up client SASL support to use a smarthost. You will also need to install the client SASL library; on Debian I think this is libsasl2-2.

Hi Vance,

I am assuming that /etc/postfix/main.cf is the only one that needs changing?

Will this work? if I am running already postfix, mysql, dovecot? I am thinking that it might affected authentication of mysql?

I don't see why it would affect mysql.

smtp_* settings apply to outbound SMTP connections from your server.
smtpd_* settings apply to inbound connnections to your server.

For Amazon SES, you're adding a new set of smtp_* settings.
