A few statistics OpenDKIM captured recently that might amuse some of you:
1) There's a slow but steady increase in signed message rates: http://www.opendkim.org/stats/report.html#signing_trend (ignore the first row, that month was skewed; also the current month is, of course, incomplete)
2) "To:" is now far and away the most munged header field invalidating signatures: http://www.opendkim.org/stats/report.html#broken_headers
3) Overall pass rates are pretty high, even when they transit MLMs: http://www.opendkim.org/stats/report.html#passfail
4) Oddly, signed messages with huge numbers of Received: header fields almost always pass verification, including one with 39 of them: http://www.opendkim.org/stats/report.html#received_correlation (let's see SPF do that!), though that message was ultimately rejected for having too many Received: fields.
