About 10:00PM last night I started receiving a flood of email -- somewhere
around 450 messages in about two hours. Yup. Everything that had been queued
up for the past 48 hours just started coming in.

Thanks a bunch for taking the time to help resolve the issue. It appears that
some servers were caching records for several days.

As for the zone file -- I threw them together at around 3:00AM the first night
of the problem so I'm astounded that they worked at all :D. I added the second
authoritative server in desperation since I knew its configuration, though not
perfect, was at least working.

There are still some details I'll have to hammer out. I'd like to setup a
slave somewhere, and have some sort of failover that will drop mail to a
secondary machine at a hosting facility.
