But I don't know, whether this is the sort of caching you are referring to.
what's a point of caching imap, except your webmail service is not locally connected (localhost or LAN) to imap server?
Asking for items 600-615 from a threaded list, sorted by something, can be an expensive operation, especially if you just asked for items 585-600 a moment ago?
fine. how about overhead of cache itself?
