Custom MIME headers by default

Hello,



In order to have Mautic work with my MTA, I need to provide a custom MIME field in the email header (e.g. x-custom-data: 123). However, I have not yet found a way to do this in Mautic. Does anybody know how this can be achieved?



Thanks in advance!

Does anyone have an answer to this? I want to add custom MIME/header too.
