Hmm, maybe you are correct

The options are:
-internet site; mail is sent and received directly using SMTP
-mail sent by smarthost; received via SMTP or fetchmail
-mail sent by smarthost; no local mail
-local delivery only; not on a network
-no configuration at this time

The first is a normal server - mail sent and received directly (of
course you need MX records set up at your domain to receive mail, but
telnet to the smtp port and you could try writing a mail from a remote
box addressed to root)
The second and third set an upstream server to use for sending all
mail - you often may need this if your ISP does not allow you to send
email directly (you often set it to mail.ISP.xxx)
The fourth means it runs locally only and you cannot send or receive
mail outside of that box

I guess the first is the only real option for sending only. If that
works for you then that should be fine, though make sure you set a
return address so you can actually test bounces etc. Without an MX
record nobody will be able to send mail to your box anyway
