 they're seeing the result of a mail loop and suppress the mail.  You
 may be able to work around this by running in <code>--invisible</code> mode.<P>
 
+If you want to support multidrop mode, and you can get access to your 
+mailserver's sendmail.cf file, it's a good idea to add this rule:<P>
+
+<pre>
+H?l?Delivered-To: $u
+</pre>
+
+and declare `<CODE>envelope "Delivered-To:"<CODE>'. This will cause the
+mailserver's sendmail to reliably write the appropriate envelope
+address into each message before fetchmail sees it, and tell fetchmail
+which header it is.  With this change, multidrop mode should work
+reliably even when the Received header omits the envelope address
+(which will typically be the case when the message has multiple
+recipients). <P>
