Add an explanation about what the example does and doesn't do.
Fix an appearantly new behavior with latex2html with quoting. (Good
incentive to work on the SGML conversion! ;)

\subsection{SMTP Example \label{SMTP-example}}
-% really need a little description here...
+This example prompts the user for addresses needed in the message
+envelop (`To' and `From' addresses), and the message to be
+delivered. Note that the headers to be included with the message must
+be included in the message as entered; this example doesn't do any
+processing of the \rfc{822} headers. In particular, the `To' and
+`From' addresses must be included in the message headers explicitly.
