this is a very good question :)
interestingly, e.g. my postfix doesn't say that's a postfix (banner
changed, of course ;) -- but when nmap'ing that machine (or any other
running postfix w/changed banner) then it gets fingerprinted correctly
and is displayed as postfix...
so even w/o a (correct) banner some tools are able to get enough
information on the service to identify it correctly.
a solution might be to work with some wrappers, altho i never digged
further into it.
