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 advan-
       tage 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>.
