It happens automatically.
If SPF record is not present, then TXT records are scanned for "spf" in record value. If it is found, then this record is parsed as SPF record.

Am I asking the right question? Is it in the DNS records that it is set?

Hmmm...I am not sure if you are looking for this answer, but let's try.

SPF are not Exchange business in regards of CREATING SPF records. SPF is either not a job of your local DNS. Also SPF for YOUR domain does not ever touch anything withing YOUR Exchange server.

Regarding SPF you take care of two parts:
- for INCOMING mails you just instruct Exchange to filter based on SPF records. Exchange does not search for SPF in your local DNS, but rather in public DNS (or cached public DNS records).

- for OUTGOING mail SPF has nothing to do with your Exchange. You may (or may not) configure SPF for your domain in PUBLIC DNS, which is responsible for your domain. Actually, for ANY server type you may or may not configure SPF for your domain, so the other end, receiving server, may (or might not) check in public DNS for your SPF records.

Here's Microsoft wizard for creating SPF record for your domain:

The resulting string "v=spf..." you add as TXT record in your pubblic DNS.
