One of the mailservers, boise is down. This is interrupting mail service. We are working on it.

Update: Service is restored. We may need to perform some additional work for a more permanent solution. Thanks for your patience.

Update: A few problems came up this morning but they appear to be resolved now. Some emails may have gotten through without being spam-checked, or may have gotten rejected by SPF rules because we accidentally set the wrong ip as the primary on boise.
