I switched from courier to dovecot over the weekend so that I could get the impersonate plugin for Roundcube working, among other things. Everything went smoothly using Till's script. The only question I have is really cosmetic I guess. With courier, the special folders like Junk, Trash and sent were under the main list of folders. Now they are underneath Inbox as a parent. This is not a huge deal, but I may want to go into users mailboxes and delete the duplicate old folders to avoid confusion. Users don't generally like change. Is this a function of dovecot configuration somewhere? I have a small enough number of users that I can just go into each mailbox and clean them up.
