Hello!

I'm a Support Engineer at Pipedrive and we have a email feature where the user can sync their email and receive/send from the webapp.

Our systems fetch the emails by their message-ID but sicne yesterday we started to receive the following error: "skipping message because it has no message id header" and because of this no emails get synced. 

We checked the raw sources of some emails and we can confirm that the message-ID is missing from the email in the provider. 

As this is impacting a lot of our customers, we wanted to confirm if there were any changes made on your side and if you are aware of this issue.

Thank you,

Shabbir Momin
