What SPF protects
SPF helps receiving mail servers decide whether a message came from an approved sender for the domain shown in the envelope sender.
What to look for
A domain should normally publish one SPF record. Multiple SPF records, missing all mechanisms, or overly broad includes can lead to delivery problems.
