SPF library and postfix policyd client
This package merges libspf2 and policyd.
libspf2 is an implementation of the SPF (Sender Policy Framework)
specification as found at:
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.
Policyd is a postfix special daemon filtering incoming mails. This
package includes the one implementing SPF, using the libraries libspf2.
Because libraries and policyd_spf are written in C it is designed for a
fast response and low system charge.
