I've set up AWS SES for Frankfurt and I can send emails just fine, but it seems that the "Email Receiving" section is disabled + all the documentation shows that only Dublin can use SES.
It seems weird to be able to send emails from Frankfurt, but not be able to receive.
Yes you are rignt, Only three regions support email receiving .
