SPF is far closer to a "service" than a TXT record.

Ok, I plead ignorant aobut SRV records and how they would be used.
Could you please help me understand them better?

For SPF, what would they look like?


Would it look like:

spf.tcp.${DOMAIN} SRV 0 0 _smtp_out

Where the user could change _smtp_out to be a different label if they
already have that subdomain?

or, would it look like:

${rev_ip_address}.spf.${DOMAIN} SRV 0 0 127.0.0.2


According to RVC2052, the last field (target) is supposed to be a
domain name, so we couldn't put the SPF options there.
