# SHORT DESC: Sendmail milter that implements SPF
# LONG DESC: SPF Sendmail milter is a lightweight, fast, and reliable Sendmail milter that implements the Sender Policy Framework anti-spam technology with the help of the libSPF2 library. It checks SPF records to make sure that email messages are authorized by the domain name from which it is coming. It has a flexible configuration with options to tag, quarantine, or block the spoofed email messages. It's an alternative for the spfmilter, spf-milter, and milter-spiff milters.
