Info:   Describes the 'tcpserver' variables defined by libSPF in the 
        libSPF Qmail patch.

tcpserver Global Vars:
----------------------

SPF_ACTION        (control/spfaction)
SPF_TARPIT        (control/spftarpit)
SPF_TARPIT_TIME   (control/spftarpittime)
SPF_EXPLAIN_STATE (control/spfexplainstate)
SPF_TRUSTED_STATE (control/spftrustedstate)
SPF_GUESS_STATE   (control/spfguesstate)
SPF_HEADER_STATE  (control/spfheaderstate)

By setting these in your environment with appropriate values you can nicely
alter the behaviour of libspf for individual persons on your network.  A great
example is by placing SPF_ACTION inside of tcp.smtp and setting it to a 0 for
127.0.0.1.

Example: 127.:allow,RELAYCLIENT="",RBLSMTPD="",SPF_ACTION="0"

This way 127.0.0.1 never has SPF checks performed on them.  I'm sure you get
the idea.
