Consume list-unsubscribe header for one-click unsubscription
Feature Summary
It would be great to consume the list-unsubscribe
header and allow one-click mailing list unsubscriptions when available.
How would you like it to work
Geary will scan emails for the presence of a valid list-unsubscribe
header. When available, users will be able to unsubscribe from a toast, above the body of the message, similar to the remote images dialogue, but at an info level.
Relevant links, screenshots, etc.
