This might be a bit tougher to accomplish than would first appear. The
reason is that notifications don't necessarily have to be via email -
they are performed by external commands which can do arbitrary things.
Nagios could be designed to understand combining multiple messages into
one using multiple To: addresses, but email is just one of many possible
notification methods (albeit a common one).
Another option would be to have Nagios send notifications to an external
app, which is responsible for grouping notifications together as you
mentioned. Sounds like a good addon project if you ask me.
