Update Mailpit to be compatible with 1-click unsubscription

Feature requests

Hi,
I’d like to test sending a newsletter from my site with the special 1-click unsubscribe feature, in order to improve the deliverability of my emails.
To do this, you need to add headers to the emails and this is done by programming. But you also need a special description in the Dkim-signature parameter.
Mailpit’s site indicates that they have implemented this.
My question is how do I implement this on Local?

Thanks for your feature request @fredericm.

This isn’t currently likely to work in Local because it uses an older version of Mailpit than v1.13.0 where the one-click unsubscribe feature was added.

I’ve shared this with the Local team so we can update Mailpit to a newer version, but I don’t have a timeline for that work just yet.
