I know there was some dissussion about how subdomains without a SPF record
would be handled but I am still clueless.
Against my better judgement, I added a:
* TXT "v=spf1 -all"
record, but it had unforseen side effects.
This is really a 'bind' question, not an SPF question. One answer would be to
use a DNS server whose configuration you understand. However, it is still an
excellent question. I wish the SPF website had some examples of proper use
of '*' in bind configurations.
