I've spent a bit of time gathering info about mail exchangers for co.za
domains to get an idea what SMTP daemons are being used. Here's a rough
stat of what being used:
Mail server %
Microsoft Exchange 9
WindowsNT SMTP 4
Lotus SMTP 2
Less than 2%: EMWAC, Apple, Connect2, Mercury, X1, AltaVista etc.
The information is not 100% correct because some little things like
CNAME'ing here and there stuffs it around.
