Get a sending domain

Bounce and complaint rates over the last 24 hours, as fractions between 0 and 1, with windowSends, the deliveries they were divided by, plus sendingStatus, which says whether the organization can currently send. The window matches the one the sending-pause rule reads. Below 200 sends that rule ignores the window entirely, so a rate over a smaller windowSends is a quotient rather than a reading. These are not a lifetime record; an identity with no traffic in the window reports zeroes.
