Do you have a URL for the site?
Am I right in thinking that Caller-ID for E-mail only lists IP addresses of
servers rather than names? In which case I would point out the following
paragraph from RFC1035 section 3.6:
"The present system attempts to minimize the duplication of data in the
database in order to insure consistency. Thus, in order to find the address
of the host for a mail exchange, you map the mail domain name to a host name,
then the host name to addresses, rather than a direct mapping to host
address. This approach is preferred because it avoids the opportunity for
inconsistency. "
In SPF you can use name-based rather than IP-based mechanisms to help ensure
cache consistency.
