This repo is meant to test email headers SES

Full details here: aws/aws-sdk-js-v3#4440

How to use

run npm install
Copy .env.example to .env
Enter the desired values in the 4 variables (ideally the TO_ADDRESS should be a gmail account - I didn't test on non-gmail addresses)
run npm run build

How to verify the issue

Send the email to a gmail account
Click on the "show original" in the email option on
Check the email headers - you should see the AWS SES headers inserted in the middle of the Content-Type header:

Content-Type: multipart/related;
    boundary="000000000000b7969b05f4993f7a"

Unlike the original issue opened on GitHub, the image still displays (I suspect I had a problem with my image which was causing the display isuse).

But unless I am mistaken those email headers are not valid?
