Eleuthria,
Have you thought about applying notifications on a per worker basis?
A worker was throwing spurious work at BTC Guild and I got about 10 notifications emails for that worker while it was mining another pool.

It's something I'll consider. If it's a big annoyance, one current workaround is hiding that worker. Hidden workers will not generate idle notification emails. Idle miner code is something I have been meaning to rewrite the script for to find a more efficient way to scan through the last share times of workers, so once I get to that (right now my focus is DDoS mitigation + new colocation), I will likely fit in the per-worker notification settings.
