I've actually got stuff in the cooker for this sort of thing, but I
hadn't added email to it:

https://bugzilla.redhat.com/show_bug.cgi?id=247772

(The bug name is misleading.)

The patch allows user-defined edge-triggered scripts for service and
node transitions.  Transition from quorate->inquorate however would be
more difficult (the transition master requires a DLM lock, which
requires quorum).

Additionally, it externalizes service/node event transition handling
into something that users can alter on the fly.  I'd be happy to work
with you on this to add a binding to the script language which would
then fire off emails.
