/etc/mail/relay-domains contains a list of hosts or IPs which can relay.
It's the simplest way.  /etc/mail/access is a bit more cumbersome to
configure.  access is used to restrict spammers and such, i.e. not
allow any incoming SMTP from specific hosts/domains.

Yes, you need a unique IP address for SSL.  mod_ssl can't read the
message (to see the host to connect to) unless it knows which key
to decode the request with.
