Is there an hyperlink type for Mutt's e-mails?

[Sébastien Hinderer]

Dear Org and Mutt friends,

Before diving into trying to implement a new Org hyperlink type for mutt
mailboxes and mails, I am wondering whether this maybe already exists?

I did check org-contrib but the only mutt-related thing I found
there is support for accessing Mairix through Mutt. Which is great
but not exactly what I am looking for.

Thanks,

Seb.
