If you don't do local delivery, but instead talk to some other server
over port 25/587, you then need to *also* ask for:

smtp authentication required (yes/no)
authentication style 
   pop before smtp (I wish that would go away)
   smtp auth (login, plain, ntlm?)
tls (never, always, if available)
username/password for that authentication step - where will you keep
those credentials securely?

That is a rather large can of worms, rather than just doing local
delivery via a local sendmail. Then, only those who care need to worry
about the grungy details of getting that mail properly forwarded
elsewhere.

Consider the case of a laptop, booting up in a hotel that blocks
outgoing port 25, trying to send cron output. Consider the same hotel
blocking port 587 (yes, some are that silly). Suppose that at the time
this laptop was configured, it was on the same subnet as the corporate
mail server, so everything just seemed to work over port 25 with no
authentication (since relaying was allowed from that subnet). Now, when
the laptop is taken home, all the cron mail silently fails.
