Web, domains and email
SPF
Abbreviation for Sender Policy Framework
In short and in plain language
SPF is a record for a domain. It says which servers may send email in the name of that domain.
Mailboxes that receive mail check the record. This makes fake senders easier to spot.
A suitable record can affect if a firm's emails arrive or land in spam.
Definition
SPF is a record in the Domain Name System that specifies which servers may send email on behalf of a domain. Receiving mailboxes check it so that forged senders are easier to spot. A suitable record can affect whether a business's emails are delivered or end up in spam.
