Sure. But it's funny to see that each and everytime I post to this list at

Well, one of those is likely from me. When I was assembling my SPF
testing setup, I had a hard time finding a tool that did what I wanted.
Mainly, take a message on stdin, add SPF headers to it, and print on
stdout. For some reason, the primary C library wouldn't compile, and I
used an alternative implementation wrapped with a shell script I
concocted.
Since I don't understand some of the nuances of SPF, I ended up taking a
shotgun approach to testing several parts of the email that could
indicate "sender". I'm not using SPF to reject emails, I'm using it to
get a feel for how many other domains have it.
