This I can understand, but what puzzles me is that David is saying that from 
the same test machine, doing nmap -sT, and telnet xx.xx.xx.xx 25, are giving 
different results.

nmap -sT does a TCP connect, and telnet does a TCP connect, so how is it 
possible for one to say that the port is open, but the other not to show the 
welcome banner?
