dovecot - May 2011 - Email being stored in "cur" folder and not being downloaded in Thunderbird

Hi,

I have recently noticed that a random number of emails are being stored 
in the "cur" folder under certain users and cannot be downloaded in 
Thunderbird. I have tried moving the emails from "cur" to
"new" but
everytime I try to download the email from Thunderbird, the emails go 
back to the "cur" folder. What could be causing this?

What is the "cur" folder used for? I had thought that the
"cur" folder
was used for IMAP but all the users here are using POP.

Also, I have tried testing this on Outlook and Outlook seems to download 
the files from "cur".

Thanks

Perfectly normal, this is the way the Maildir format works.

No, the way the mail is stored and the way it is accessed are two
different things.

Gr??e,
