Today was all about tweaking email and trying to get it to the point where alerts are not flooding the users, but are also not delayed so much for consolidation that they're pointlessly late (getting a message that says, in effect, "your CMTS crashed 30 minutes ago" isn't much help).

Along the way I burned almost an hour discovering that Twisted's ESMTP support isn't ready-for-prime-time yet (though it should get better in 2.0, thanks to the Chandler folks, it's still not going to be an elegant API).
