<pre>Although LMTP is an alternative protocol to ESMTP, it uses (with a
few changes) the syntax and semantics of ESMTP. This design permits
LMTP to utilize the extensions defined for ESMTP. LMTP should be
used only by specific prior arrangement and configuration, and it
MUST NOT be used on TCP port 25.</pre>
