NAME

       tumgreyspf - an external policy checker for the postfix mail server

SYNOPSIS

       tumgreyspf [ configfilename ]

DESCRIPTION

       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  <jafo@tummy.com>  or  to  me,  the  Debian  maintainer,  Thomas  Goirand
       <thomas@goirand.fr>.
