Header encode?

I’m using Mac Beta eM Client and see the following in every email near header… Why? How do I turn it off?

“Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Content-Type: text/html; charset=utf-8”

Can you post a screenshot? It’s likely and issue with the server you are connecting to not following the IMAP protocol specification correctly. You can enable the logs in Settings -> Diagnostic Logs and send them to our support for analysis.

I sent the logs and screenshot above.
