Notmuch deals with the "replied" tag in two ways.

First, the tag is synchronized with the maildir flag R, both ways. This
is the "R" in the filename after ":2,". See [1] for details.

Second, the notmuch-emacs interface adds the "replied" tag upon sending
the reply. You can customize this tag, but note that only "replied" gets
synchronized to maildir flags.

If you use a MUA that doesn't either add the R flag or call notmuch to
add the "replied" tag, you'll lose this bit of information.

You might also find [2] relevant.

BR,
Jani.
