Opening the message takes almost exactly (I have timed it with a stopwatch many times) 77 seconds to open. Every other aspect of the horde server works fine and responds immediately.

We have a squirrelmail webmail interface that works with the same imap server. It does not have this problem. We have other imap interfaces that work fine. The problem is just some users of the horde imp software, and specifically only with calling message.php through horde.

The server acks the response, but the get request does not show up in the webserver logs. Then, for 77 seconds, nothing apparently happens on either the client or server side (except for the sidebar.php refreshes, which work fine through this whole process). Then, 77 seconds later, the get request appears in the webserver log, is responded to immediately, and the message appears in the browser interface.
