I'm looking for install base numbers (estimates, averages, whatever)
for Berkely sendmail, Sendmail-IDA, Smail, mailsurr, and X.400 (sum
of implementations).  I know these are slightly odd catagories to
compare, but does anyone know of an magazine article, book, doc
on an ftp site, or newsgroup FAQ that might have relatively current
numbers (within the last year or so) for any of these?

If I get a lot of responses, I'll post the results.

	My humble thanks,
