I am planning to transition some email SMTP use to Amazon's SES. I have several domains and sender email addresses verified with SES and am testing in the sandbox.
From what I can tell, SES SMTP credentials are not tied to any specific domain or sender email address within my AWS account.
Is this correct?
There is no mention of a domain or email address when generating the SMTP credentials, and in my initial testing I can use any of my SMTP credentials with any of my verified sending email addresses.
Is there a way to have a set of SES SMTP credentials that only work with one domain, or only with one sending email address? It would seem that the alternative is to segregate your sending email addresses out to separate AWS accounts if you want to have SMTP credentials that only work with some email addresses and not others. Why would that be the design? It feels so odd that I suspect I am not understanding something around the intentions behind the relationship between the SES SMTP credentials and sender email addresses and domains.

Currently AWS does not support the above separate SMTP credentials for particular domains. Depending on the amount of domains you are planning to use you can create separate AWS accounts and tie the SMTP credentials to those domains.
