The Sender Policy Framework (SPF) is one part of the SPF/SRS protocol
pair. SPF allows email systems such as Sendmail, Postfix, Exim,
Zmailer and MS Exchange to check SPF records and make sure that the
email is authorized by the domain name that it is coming from. This
prevents email forgery, commonly used by spammers, scammers and email
viruses/worms.

This package contains simple utilities that use libspf2 to test and
query SPF records.
