yes... all you have to configure to be set is a file like this https://github.com/dyne/JaroMail/blob/master/doc/Accounts/de...

there can be one for each different account inside Mail/Accounts.

I think Mutt is really great software, but I cannot live without tab completion from my addressbook and I need it without spending 1h to configure it every time, so that's the gist of it...

What do you use for your address book? I just use mutt's alias so have tab-completion out of the box.

Given the reference to notmuch, I'm guessing harvesting addresses from/with notmuch index?
