[Dovecot] Missing Messages on IOS device

[David Morsberger]

I just converted my old server running UW/Panda to a Mac Mini Server running Mountain Lion (ML) Server. I'm using the postfix / dovecot setup provided by Apple.

My IMAP clients are not showing all my emails. The Mail App on my iPhone and iPad is behaving the worse. I can see the emails that are not showing up in the cur directory.

The ML Mail App is stating there are 3854 emails in my INBOX. There are 3948 files in the 'cur' directory ('ls cur | wc -l' returns 3948). Other mailboxes and directories have the same behavior. I'm not sure what to expect here.

My method of conversion was to bulk copy (drag and drop) all the messages from one the UW server to the Dovecot server using the Apple Desktop Mail App in Mountain Lion. 

Any idea why these messages are not showing up on my devices and how I can get them to show up?
