add postfix-policyd-spf-python plugin

[lynix]

Very simple but useful plugin to monitor postfix-policyd-spf classification results. Written by me some time ago, but still works :)

Could you pick a license for it, please, and add it to the plugin?

Either a copyleft or permissive opensource license would be fine, but it should be explicitly stated which license to use in the plugin.

Sure, I'd like to go with the MIT license (although I don't care much, so if you've got a better suggestion I'm open to it). Shall I paste the entire license in the script or just state the name of the license?

I'm a bit irritated because I've seen many plugins without any license information (partially even without author information).

For most plugins in the "munin" repo, we just state the name of the
license in the plugin. (MIT/Expat, MIT/X11, GPL-v12345, Apache-2.0,
etc…)

Some plugins have the entire license text. I'm fine with both
alternatives.

Sorry about that. :/

Yes, there are many of those, unfortunately. Tracking down previous
authors, in case that becomes necessary, will take a lot of time. The
alternative may be to drop them altogether.

Thanks for the info :) I've added the license commit.
