Name : libspf2 Product : Fedora 35 Version : 1.2.11 Release : 1.20210922git4915c308.fc35 URL : http://www.libspf2.org/ Summary : An implementation of the SPF specification Description : libspf2 is an implementation of the SPF (Sender Policy Framework) specification as found at: http://www.ietf.org/internet-drafts/draft-mengwong-spf-00.txt SPF allows email systems to check SPF DNS records and make sure that an email is authorized by the administrator of the domain name that it is coming from. This prevents email forgery, commonly used by spammers, scammers, and email viruses/worms.
A lot of effort has been put into making it secure by design, and a great deal of effort has been put into the regression tests.
