# Z-Push: The Microsoft Exchange protocol server.
# Mostly for use on iOS which doesn't support IMAP.
#
# Although Ubuntu ships Z-Push (as d-push) it has a dependency on Apache
# so we won't install it that way.
#
# Thanks to http://frontender.ch/publikationen/push-mail-server-using-nginx-and-z-push.html.

source setup/functions.sh # load our functions
source /etc/mailinabox.conf # load global vars
