It sounds like you're talking about a web server, which talks to a very
different class of machines than normal smtp servers. Barring the minority
that send mail from their dialup/dsl/cable modems, most smtp traffic comes
from other ISP's mail servers. I would hope that administrators give greater
attention to proper configuration of their servers than to their dial pools.
While I get (and tend to agree with) the point you're trying to make, I
think the numbers could be adjusted to be a little more accurate. Maybe run
log analysis on your smtp logs, and compare them to what you got for web
logs? That might be interesting to see.
