If you do much work in email / spam control, you end up seeing some of
the many ways that folks manage to screw up their DNS records. But this
one is amusing. Two disconnected sets of dns servers, both sets
referenced from the .com servers. Each set has their own serial number
and different content. Clever.

Note the extra set of quotes which breaks the spf record on the version
from the azure servers. Either nobody reads sys...@pressganey.com, or
they don't care. A note was sent there 30 days ago.
