Hello, I have some mailing list archives kept in mailboxes over IMAP. I have header caching enabled on 1.5.17. Usually when I switch to those folders, mutt "evaluates" the caches, which is a process that's considerably faster than "fetching the headers" (indeed, that's the point of caching). But sometimes lately, when I switch into one of these folders, mutt will begin fetching anew as if I had no cache built up. Well, that's not quite true: mutt begins fetching anew as if I only had a small fraction of the cache that I actually do. I've got ~15K mails in this folder. Sometimes for no reason mutt will start fetching headers starting with a seemingly random #, like 4517 or 3387. This is really annoying, since fetching takes a *long* time with 15K mails.
Anybody got a clue? I've never had this happen before until recently. -gmn
