Hunt him down and beat him with a trusty clue-by-4.

SPF uses "example.com" TXT records, and now special SPF type records
(type 99) that not many people supprt.
DKIM uses "_policy._domainkey.example.com" TXT records and
"selector._domainkey.example.com" TXT records.

Different places means that they can both exist in the zone at the same
time, thus no problems.

Anyone know a *nice* site that is well set out and easy to read for DKIM
information? dkim.org is kinda ... IEEE looking.
