Horde, IMP, and imapproxy

So it turns out that the cache in imapproxy that we turned on yesterday has a problem. First of all, it seemed to work great. I think webmail was more responsive and there was a reduced load on our mail disks. However not all was well. It seems like some times when you deleted a message, it was still displayed in your inbox. Also some times when you read a message, and then went back to the inbox, the message still looked like it was unread. Unfortunately this means we had to turn off the cache. Oh well, it was worth a try.
