How to use Amazon Simple Email Service for only verified email sender addresses
I have a similar setup, but I have solved this outside CiviCRM. In CiviCRM, I configured the mail() send option. The effect is that the mail is routed by the local Mail Transport Agent. On my system, I use postfix for this task.

Postfix can be configured to relay an email to an email service dependent on the email address. Use to do this the sender_dependent_relayhost_maps parameter. An example can be found in this answer on the Unix site.

It is a good practice to send bulk mail with Amazon SES to prevent the email to be marked as spam.
