This wouldn't be too helpful as you can also identify an Exchange server by
seeing how it responds to commands. For example the EHLO option:
220 XXX ESMTP Server (Microsoft Exchange Internet Mail Service 5.5.2650.21)
ready
EHLO
250-XXX Hello [YYY]
250-XEXCH50
250-HELP
250-ETRN
250-DSN
250-SIZE 0
250-AUTH LOGIN
250 AUTH=LOGIN
