Wrong. Completely wrong. Any UNIX-like box with qmail can be configured to send mail out. My laptop, for example. But my domains only receive mail at the servers designated as MX hosts in DNS.
Your idea that an outbound mail host should be listed in DNS indicates a complete misunderstanding of the purpose of an MX record. These records indicate to other MTAs where they should deliver mail *to*, not where they should accept mail from.
