An invalid SPF record has issues that impede the authentication process and sometimes allow hackers to send fraudulent emails on behalf of your company. On the other hand, valid SPF records for organizations help recipients’ servers identify if senders who have sent messages using their domain names are genuine or not.
In case the sender isn’t authorized, the email would be either marked as spam or denied to enter the mailbox. This depends on the type of ‘all’ tag the domain owner has used in their SPF TXT record.
Invalid SPF DNS records for business domains can be fixed by correcting misconfigurations, syntax errors, typos, etc. Some common syntax error examples are- the use of the mx or ptr mechanism and the +all tag. You also need to check if all the IP addresses currently being used for sending emails have been added.
