Mail *clients* (e.g. Eudora, Outlook) usually require a relay.  A
full-blown MTA like sendmail can do its own mail delivery directly to the
destination.

However, many ISPs block outbound SMTP, to prevent their users from
hijacking open mail relays to send spam.

The real root servers don't allow you to do zone transfers, so you'll have
to synchronize some other way.
