Doug, are you sure that's what you meant to say? The sentence is a
bit ambiguous. Are you really saying any host that sends mail (is an
SMTP client) MUST also host an listed SMTP server?
You are right. This should have been pubic MTAs, meaning those that
send email using port 25 without authentication. All other sources
should be restricted in some fashion, perhaps by ACLs or
authentications.
