It is also reasonable for a machine to only need to deliver locally generated mail.
It wouldn't be much fun if all machines did that.
I like the fact that it is locked down by default. Then again, I can remember when most mail servers were open relays. You could spoof a message by telnetting to port 25 on the mail server you wanted the message to come from, and feeding it your message. The server would then happily relay the message to the destination, and it would have all the correct headers...
Sendmail does not relay unless you explicitly permit it to by defining the addresses allowed in the access database or set up smtp authentication - and it hasn't for years.
