[dkim-ops] Is anyone home?

Is anyone actually using DKIM?  Since switching from dk-milter to
dkim-milter I have yet to see a DKIM-signed message come here except
for my own DKIM-signed mail coming back on mailing lists.  By way of
contrast, yesterday 34% of the mail making it past my pre-milter
filtering was from domains with SPF records.  It appears DKIM has a
long ways to go to catch up ...

Anyway, dkim-milter seems to have a problem handling cases involving
sendmail's GreetPause feature.  Every time (well, I think it's every
time) an smtp connection blasts SMTP commands at my MXs without
waiting for an EMTP greeting, I get logfile messages like these:

Jul 20 16:21:24 mx0 sendmail[7818]: j6KKHo2d007818: Milter (dkim-filter): read returned -1: Connection reset by sv.e103gng.com
Jul 20 16:21:24 mx0 sendmail[7818]: j6KKHo2d007818: Milter (dkim-filter): to error state
Jul 20 16:21:24 mx0 sendmail[7818]: j6KKHo2d007818: Milter (dkim-filter): init failed to open
Jul 20 16:21:24 mx0 sendmail[7818]: j6KKHo2d007818: Milter (dkim-filter): to error state
Jul 20 16:21:24 mx0 sendmail[7818]: j6KKHo2d007818: rejecting commands from sv.e103gng.com [66.62.19.10] due to pre-greeting traffic

This didn't happen while running dk-filter.  This seems to have no
effect other than filling up logfiles ... connections that wait for
the sendmail greeting get processed normally, although I'm not certain
they *all* do.

Does anyone else see this?  More importantly, does anyone know what
causes it?  I'm a tad weary from mucking around in the bowels of
sid-filter, so I thought I'd ask before trying to chase this down.
