That adds a new "spf" condition to Exim's ACL rules. See
"experimental-spec.txt".

That runs an external program, instead of using the Exim spf support.

Run a second copy of the relay on a different port, and debugging turned
on and some extra debugging, like so:

exim -oX $PORTNUM -d+acl,expand -bd

Telnet to that port, look at the debugging output, which will include
more indepth information about ACL testing and string expansion.
