Sendmail: Refusing Connections, and authentication/relaying

Two prime issues for me on this one.
First, and most crucial: sendmail seems to be set up and working fine; I can
send mail from the local machine to other hosts.
However, I haven't been able to convince it to accept SMTP connections from
other hosts. cyrus-imapd seems to be set up and running fine, but the smtp
port is, according to a friend, filtered and unavailable. I've been trying to
scan through the sendmail configuration readme as well as the FreeBSD
handbook, and will continue looking, but as of this time I haven't found a
way to open it up to outside connections. FreeBSD 5.1, sendmail 8.12.9, no
firewall presently running.
Once I can get sendmail accepting connections, it brings me to point B: Is it
possible to set up sendmail so that local users can send to wherever, but
remote users have to authenticate to do so(and can basically use my server as
a remote mail host)? I don't want to run sendmail promiscuously, but it would
be very nice if I could convince it to allow authenticated remote users to
send to anywhere.
Or am I confused on the definition of "relay"? If it doesn't apply to people
who use authentication, I'm already fine, and can just work on setting up
