+<sect>SMTP Support (OPTIONAL) <!--{{{-->
+
+<p>Mutt-ng can be built using a library called ``libESMTP'' which
+provides SMTP functionality. When <tt/configure/ was called with
+<tt/--with-libesmtp/ or the output <tt>muttng -v</tt> contains
+<tt>+USE_LIBESMTP</tt>, this will be or is the case already.
+
+<p>To enable sending mail directly via SMTP without an MTA such as
+Postfix or SSMTP and the like, simply set the <ref id="smtp_host"
+name="$smtp_host"> variable pointing to your SMTP server.
+
+<p>Authentication mechanisms are available via the <ref id="smtp_user"
+name="$smtp_user"> and <ref id="smtp_pass"
+name="$smtp_pass"> variables.
+
+<p>Transport Encryption via the StartTLS command is also available. For
+this to work, first of all Mutt-ng must be built with SSL or GNUTLS.
+Secondly, the <ref id="smtp_use_tls"
+name="$smtp_use_tls"> variable must be either set
+to ``enabled'' or ``required.'' In both cases, StartTLS will be used if
+the server supports it: for the second case, the connection will fail if
+it doesn't while switching back to unencrypted communication for the
+first one.
