notmuch can generate temporary maildirs as well with this script:<p><a href="http:&#x2F;&#x2F;git.notmuchmail.org&#x2F;git&#x2F;notmuch&#x2F;blob_plain&#x2F;HEAD:&#x2F;contrib&#x2F;notmuch-mutt&#x2F;notmuch-mutt" rel="nofollow">http:&#x2F;&#x2F;git.notmuchmail.org&#x2F;git&#x2F;notmuch&#x2F;blob_plain&#x2F;HEAD:&#x2F;cont...</a><p>However, in my experience mutt-kz is much faster. Plus, you get tagging everywhere (if you use it) and threads can be reconstructed across folders (helpful when your own mails are in a &#x27;Sent&#x27; folder).
