You also have to take into account the number of people that hide Exim
behind fake Sendmail (and other) banners in an attempt to fool would-be
hackers!!! <grin>
I know of at least 30 sites that do this...
Telnetting to port 25, typing 'help' and checking the results usually
reveals a lot more than just a banner.

But what sort of people speak to your mail servers? Presumably, these
figures could simply be skewed by spammer's preferences. Then we also have
to take into account the type of business that you are in.
