Is your feature request related to a problem? Please describe.
As a Nextcloud Mail user I want to have the option to have emails automatically deleted past their "expiration date". This is an initiative documented at https://www.zerocarbon.email/argumentation/. When senders take part of the initiative they send a simple header with a date.
Describe the solution you'd like
Offer an opt-in to value the header and have the emails automatically deleted. For best control I would like to have the option to stop the expiry of a specific email.
Describe alternatives you've considered
