I've successfully setup a VPS as a mail server following this tutorial: http://www.howtoforge.com/virtual-users-and-domains-with-postfix-courier-mysql-and-squirrelmail-ubuntu-12.04-lts
Most everything is working now, but one annoyance I'm having is that when I connect to my mail account through Thunderbird all my mail folders (send, drafts, etc) are organized as a sub-folder of Inbox.
I've been able to fix this in Thunderbird by going into account settings and setting the IMAP folder path prefix to "Inbox". This solution, however, isn't ideal. I'd like to not have to do this on every client I connect with, for every account that connects.
Does anyone know if it's possible to configure this in courier on the server side so that it gets set automatically? Are there any other options that would solve this problem?
