Virtual mailboxes (described by Notmuch queries) can now configured for each account in NeoMutt.
Plus, it is possible to disable Notmuch section for a specific account.
Neomutt will run the given command (which can be a string or a path)
and take the output from stdout and use it as the signature for your
email.
