Yes, locally at least. You can disable port 25 though.

No.

Don't trust that, if you want to be real sure, try to actually relay e-mail 
through it... or do some SMTP hacking.  This is what I get with (basically) 
the default sentinix config (it's somewhat modified, but not much):

user-d/[email protected](~) nc sentinixbox 25
220 sentinixbox ESMTP Postfix
HELO test.com
250 sentinixbox.com
MAIL FROM: [email protected]
250 Ok
RCPT TO: [email protected]
554 <[email protected]>: Recipient address rejected: Relay access denied
QUIT
221 Bye
