DKIM + Nodemailer on docker

[cedricbraekevelt]

Hello,

I'd like to use DKIM via nodemailer as a mailing agent.
I'm using 'mail__options__secure true' already and tried to follow this guide for nodemailer: https://nodemailer.com/dkim/
However I think the following properties don't exist or are incorrect:
mail__options__dkim__domainName
mail__options__dkim__keySelector
mail__options__dkim__privateKey

Is there anyway to use DKIM with nodemailer inside Ghost?

PS: Running in docker and mailing is working fine, just DKIM is not.

Kind regards,
Fruitychocolate
