+Debugging
+---------
+
+Mail mostly happens from frontend.  The PHP there would send the email.
+If you have a received message in hand, you can see the trail of servers
+in the Received: headers.  It starts from PHP.  It goes from there to
+/usr/sbin/sendmail (exim4 on those systems) and then out to
+eggs.gnu.org, then to lists.gnu.org and out to the mailing list for
+delivery.
+
+If there is an error in sending the PHP and Apache combination should
+log an error to the frontend:/var/log/apache2/error.log file.
+
+All of the mail status should be logged to
+frontend:/var/log/exim4/mainlog.  When a message is sent you should see
+the transaction logged there.
+
+Logs are rotated.  If you are looking back into the past you will need
+to look through `mainlog.1` and older to find the transaction.
+
+You can see messages pending for delivery in the mail queue with the
+`mailq` command on frontend.
