The manual doesn't tell anything about maildir support, mostly because
the person who contibuted the mailstat code didn't include a man patch
to go with it.  One side-effect of that code is that when checking new
mail, zsh can't tell that maildirs are directories -- mailstat returns
data as if the folder were one huge file.  That's why it's so expensive
in the absence of the (broken) optimization.

} To understand this fully I seem to need to make a distinction: you say

Exactly one named in the value of the mailpath parameter.

That should work, but see below.

It does matter; you have it right.

} (a)  From within either mutt's index or pager, I press `e' in mutt
}      to edit the raw message;

If you have mutt (or any of several other mail programs) running
continuously in another window, zsh won't regularly notify you of new
mail no matter what the mailbox format is, because there is a race
between mutt and the shell to see which one finds the new message
first.  Once mutt finds the message and adds it to its index, the
file access time will have changed and zsh won't consider the message
to be new any more.

If your maildirs are on NFS-mounted file systems, NFS attribute caching
can also affect whether zsh correctly detects new mail.
