Hmm. I have a small tool that is run during my ACLs and adds the
following headers to each incoming mail:
X-p0f-genre: FreeBSD
X-p0f-genre-details: 4.6-4.9
X-p0f-distance: 8 hops
X-p0f-link: ethernet/modem
X-p0f-uptime: 7600 hrs
[or some others depending on the actual information p0f gives me]
Then serves as input to my statistical spam filter.
What exactly does amavisd do with this information?
