I've never set it up, but there's a couple of options.
1) Authenticated SMTP -- I think this can use LDAP or PAM or other
2) "POP before SMTP" -- I don't know how to do this one, but it's common to

an hour during which it can use the mail server for SMTP. (with that hour
getting refreshed every time POP is used) Or maybe 5 minutes instead of an
Allowing a wandering IP address to use you for relay is probably a bad idea;
though if it's inside of a consistent network block, allowing that block of
IP addresses (especially if it's in a /24 or two) isn't much of a risk.
