I would totally exclude the server that generates the logs and just
use the 250 responses from the remote SMTP servers. Unless it's
someone like AOL, I don't think that ignoring the local system will
have much bearing on the stats.
I wouldn't bother chasing down the MX and then probing it, from the
perspective of Sendmail vs qmail vs the-rest, the queue-id responses
are sufficiently distinct with a few pattern matches.
The best server logs to look at are probably those that are running
diverse-interest mailing lists. ISP logs - regardless of whether they
are running qmail - are probably fine since we're not counting local
deliveries.
