I am looking for a command line SPF query utility.
It needs to be small/lightweight, preferably written in C. I can't use
perl or other scripts, since I may need to be exec'ing it on every
message, and script interpreters would be too expensive.
Is there such a thing?
If not I may need to write one, any pointers are appreciated.
Please don't respond if all you are going to say is 'why do you need that'
or 'use a mta that has support for it' or the like. For the moment I am
just interested in the question above.
Thanks
