[Dovecot] Ampersand in Folder names causing folders to disappear?

Hi All,

Dovecot 1.0.rc7

Not sure if this is a problem with Outlook, or with Dovecot, or to do with encoding in Linux.

Whenever a user enters an ampersand into an IMAP folder name, it dissapears from outlook. These folders appear on the ext3 filesystem as &- for example

drwx------ 5 mailusers mailusers 4096 2006-10-10 17:54 .INBOX.Networks.London Networks.NDCs.WH&-P joint working

Any pointers or previous experience anyone has of this would be very gratefully received.

Regards, Mark
