+LMTP support.<span style="font-family: monospace;"></p>
+<p>There are actually <i>two</i> LMTP sockets. One is called
+<tt>lmtp.socket</tt> and the other is called <tt>lmtp-unfiltered.socket</tt>
+(both are found in your Citadel directory). The difference should be
+obvious: messages submitted via <tt>lmtp.socket</tt> are subject to any
+spam filtering you may have configured (such as SpamAssassin), while messages
+submitted via <tt>lmtp-unfiltered.socket</tt> will bypass the filters. You
+would use the filtered socket when receiving mail from an external MTA such
+as Postfix, but you might want to use the unfiltered socket with utilities
+such as fetchmail.</p>
