How you would know: You should see something like this:

$ telnet remote_machine 25
Trying 192.168.1.1...
Connected to remote_machine.mydomain.com
Escape character is '^]'.
220 remote_machine.mydomain.com ESMTP Sendmail 8.14.3/8.14.3; Fri, 24 Feb 2012 
19:44:05 -0500 (EST)

Note the 'Sendmail'. I don't have a postfix server handy, but presumably 
it would not emit the S word.
