Mail filter for Sender Policy Framework verification
Description
smf-spf is a lightweight, fast and reliable Sendmail milter that implements the
Sender Policy Framework technology with the help of the libspf2 library. It
checks SPF records to make sure that e-mail messages are authorized by the
domain that it is coming from. It's an alternative for the spfmilter,
spf-milter, and milter-spiff milters.
