Running a pretty basic setup of imap +pop3 on version 2.1.10
Users are able to create folders in imap that contain "&" the folder on the backend reflects "&-" as it should, you can list folder, but then when you relog into imap then decides it can no longer subscribe to this folder due to invalid UTF characters. Essentially allowing users to lock themselves out by using a very common character in a folder name. Might one of the imap client compatibility plugins in imapd cause this quirkiness ? Should I be coming at this from another direction? Is this a bug?
