commit emails from a central server with bzr 2.6

[Glenn Morris]

Last question, I hope... :)

If I have the bzr-email plugin installed on my local machine, then when
I make a commit to the Emacs repo on Savannah, my local machine also
tries to send a commit email. This happens to fail (because my local
machine isn't configured to send external mail), but I'd still like to
stop it. I thought that adding an entry to ~/.bazaar/locations.conf on
my machine might do this:

[bzr+ssh://USERNAME@bzr.savannah.gnu.org/emacs/*/]
post_commit_to = False

But it just tries to send email to "False". Same with None, or [].
Is there a way to disable it locally, while still having it enabled on
the server?
