setting up SMTP server hostname

[branko77]

Hi, is there a need to set up SES SMTP hostname somewhere? Not sure I understand how it works, how it knows which SMTP to use? If I switch to my DR site for instance from eu-central-1 to eu-central-2 is there anything I need to change/add in my configuration? I use this relay as a sidecar container inside of a pod, and so far I successfully tested in one region without any additional arguments or env settings.
