[imp] IMP 4.2 (RC4) / Mail.app interaction - changes made in mail.app not reflected in imp

[Liam Hoekenga]

We're getting reports from our helpdesk that changes made in OSX  
Mail.app (deleting messages, refiling them, changing flags) don't get  
reflected in IMP.
I can't replicate it, and I've asked the consultants who can for more  
details (browser, version of OSX, whether they're using Mail.app and  
IMP simultaneously, etc) and hopefully a guide on how to replicate the  
issue.

I'm guessing it's some weird IMP message cache vs Mail.app message  
cache conflict.

We're using 4.2RC4.

Has anyone else seen something like this?

     The problem is that when he makes changes in Apple Mail (IMAP), such as
     deleting a message, changing the read/unread flag or moving a message
     from Inbox to an IMAP folder, the changes are not reflected in web-mail.
     I replicated the behavior. I tried Apple Mail's Synchronize IMAP Mailboxes
     function and tried refreshing web-mail, but the changes I made in Apple
     Mail were not reflected in web-mail.

     I had a customer call today who complained that, since last week's
     upgrade, even though he deletes mail while in Apple mail client,
     deleted messages show up as unread mail the next time he accesses
     webmail.

     I confirmed this with my own account.

     I was able to determine that, if he tells the mail.app to erase
     deleted messages, they will indeed no longer be seen when he goes
     into webmail.
