# runs mbsync, with pre-hooks and post-hooks
# by default, first runs imapfilter
# and after indexes with notmuch
#
# To run without invoking any hooks or retry attempts,
# run `checkmail raw`
# this will simply invoke a single isync run on all
# boxes with the correct config file set.
#
# for more advanced, per-account/channel hooks, see
