How can I remove the "sent via" in my emails

When sending email from platformsh the recipient gets a ‘via platformsh’ appended. I understand platformsh uses sendgrid. How should i configure my domain so I don’t get the ‘via’ platformsh message?

You have to set up DKIM on your domain. Unfortunately we do not offer white-labeling them.

Please refer to :

You will have to set up your own sendgrid account (or another email provider) if you want to enable white-labeling.
