+libspf2 implements the Sender Policy Framework, a part of the
+SPF/SRS protocol pair. libspf2 is a library which 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.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
