Temp mail

Upon approval I will switch to @ipa alert lists (sot_ace_alert to @cfa (google) - sot_ace_alert@ipa does not exist) at 2 pm on 8/15 and backout to @head (majordomo) at 9 am on 8/18.  Alerts from OCC (c3po-v) can be sent to @ipa directly, bypassing the HEAD mail server during the power outage.
