Feature Request: Filter Emails by Specific Header (Content-Type)

[Philipp0205]

Hello,

I'm encountering a frequent scenario where I receive numerous meeting invitations via email. I'd like to automatically organize these by moving them to a specific folder.

Currently, I'm considering using the Content-Type header to identify these specific emails. The relevant invitations typically include this header:

Content-Type: text/calendar; charset="utf-8"; method=REQUEST

Integrating such a feature would greatly enhance email organization for similar use cases.

Thank you!
