How to properly forward Service Desk emails within cPanel?

I tried to create a Forwarder to my project’s service desk email but the issues are not created.

I confirmed the emails are indeed leaving my server from the below lines in exim log:

This is relative to the gitlab.com instance of gitlab

Bump, I believe this may be related to the parsing of the email headers in Gitlab.
Soon I will provide a full headers dump of an example email that gets ignored.
