Alert rules

Hi,

I've been asked to try to make alerts only send 2 emals, at most, and
still send a RECOVERED message when things recover.
As a quick test, I set DURATION<30, and REPEAT=15, and after forcing a
service down, for over an hour, achieved the
two email alerts - but after bringing the service back up, did not get
sent a recovered message.

Is it possible to do this?
