Can more than one SPF record be present on the same domain? The answer is no; if a domain contains more than one SPF record, SPF will fail with a PermError.

A TXT record in the DNS known as an SPF record is one that begins precisely with “v=spf1” and is followed by a variety of mechanisms and/or modifiers.

A domain’s TXT records with the identical first character “v=spf1” are fetched to start an SPF check:

• It returns “none” if no such record is found 
• If more than one such record is discovered, it returns PermError.

For instance, if yourdomain.com has two TXT records:

All emails sent on yourdomain.com’s behalf will include PermError SPF authentication failures.

You must include all the mechanisms that have legitimate IP addresses in a single SPF record in order to fix the issue, as demonstrated below:

All of these prerequisites must be satisfied for SPF authentication to succeed:

• Your domain has exactly one SPF record
• which has the proper syntax
• a maximum of 10 DNS lookups
