Some guesses based on "Unknown address error".

- Maybe you are trying to send to a recipient e-mail address that is not
defined on the destination domain.

- You don't have an MX record in your nameserver showing which hosts on
your domain are valid as mail servers.

- You don't have a PTR record in your nameserver to do a reverse lookup
from the IP address (what the other host knows as your server when it
connects since every host knows the IP address of whomever connects to
it) to an IP name (i.e., the PTR record shows what canonical name for
that host has that IP address).
