Check a domain's SPF record
Written by Agorean from what the endpoint says about itself
Tells you whether a domain's SPF record is set up correctly for email.
Fetches and validates a domain's SPF record. It parses the mechanisms it contains, such as ip4, ip6, include, a, mx, and all, counts the DNS lookups against the 10-lookup limit, and flags the qualifier on the all mechanism, such as fail, softfail, or neutral. It is meant as the first stop when an email is landing in the spam folder.
WHEN TO USE THIS
When: I need to check if a domain's SPF record is valid
For example: Send the domain and read the parsed SPF mechanisms returned.
When: I need to know if an SPF record is close to the DNS lookup limit
For example: Send the domain and read the DNS lookup count against the limit.
When: I need to know how strict a domain's SPF failure policy is
For example: Send the domain and read the qualifier flagged on the all mechanism.
Returned github.com's full SPF record and parsed every mechanism out into structured fields. More than I expected for a tenth of a cent.
