I have set up a MAIL FROM domain with Amazon SES by following their instructions: https://docs.aws.amazon.com/ses/latest/DeveloperGuide/mail-from.html

They have verified that the DNS records were set correctly.

However when I send an email using SMTP and the server being: email-smtp.eu-west-1.amazonaws.com I get the following error on mail-tester.com: HEADER_FROM_DIFFERENT_DOMAINS From and EnvelopeFrom 2nd level mail domains are different

So I tried sending it using the subdomain (MAIL FROM domain) for which I created an MX record and a TXT record, but the email software (Sendblaster) says that the server cannot be found. Do I need to also set up an A record for this to work? Or is the solution elsewhere?

So it turns out that you need to set the MAIL FROM domain for each verified email and not just for the domain.

This solved it.
