       tumgreyspf - an external policy checker for the postfix mail server


       tumgreyspf [ configfilename ]


       Tumgreyspf  can  optionally  greylist  and/or use spfquery to check SPF
       records to determine if email should be accepted by your server.

       SPF is information published by the domain owner about what systems may
       legitimately  send  e-mail for the domain.  Greylisting takes advantage
       of spam and viruses that do not follow the RFCs and retry deliveries on
       temporary  failure.  We use these checks as part of our mail system and
       have seen several orders of magnitude reduction in spam,  lower  system
       load, and few problems with legitimate mail getting blocked.

       Tumgreyspf  uses  the  file-system  as  it's  database,  no  additional
       database is required to use it.

       This man page is a place holder for whoever wants to  write  a  doc  to
       this.  Feel  free  to  send  it  to  the  upstream  Sean  Reifschneider
       <> or  to  me,  the  Debian  maintainer,  Thomas  Goirand
