Is it missing in the mail server or just on the client? What does your 
server layout look like?

We had a similar issue with Outlook and AppleMail where the uidlist 
would change just enough to wipe out their local index. People would 
tell us that they could see the E-mail in webmail but not in their client.

We haven't had the issue in a long while, but it was painful while it 
lasted. The key to resolving the issue had to do with upgrades to the 
dovecot version - we currently just made the jump to 1.1.11 and it seems 
to be working well.
