Hi Michael,
	I'm running dovecot 1.2beta5. I'm not sure which version does not  
support folders with subfolders, but 1.2x does. Here are some imap  
commands to prove it works.

2 list "mail" *
* LIST (\Noselect \HasChildren) "/" "mail"
* LIST (\NoInferiors \UnMarked) "/" "mail/folder1"
* LIST (\NoInferiors \UnMarked) "/" "mail/folder2"
* LIST (\NoInferiors \UnMarked) "/" "mail/Trash"
* LIST (\Noselect \HasChildren) "/" "mail/anotherfolder"
* LIST (\NoInferiors \UnMarked) "/" "mail/anotherfolder/mbox1"
* LIST (\NoInferiors \UnMarked) "/" "mail/foo2"
* LIST (\NoInferiors \UnMarked) "/" "mail/foo3"
2 OK List completed.
3 list "mail/anotherfolder" *
* LIST (\Noselect \HasChildren) "/" "mail/anotherfolder"
* LIST (\NoInferiors \UnMarked) "/" "mail/anotherfolder/mbox1"
3 OK List completed.
4 delete mail/anotherfolder/mbox1
4 OK Delete completed.
5 delete mail/anotherfolder
5 OK Delete completed.
6 create mail/anotherfolder/
6 OK Create completed.
7 create mail/anotherfolder/mbox2
7 OK Create completed.
8 list "mail/anotherfolder" *
* LIST (\Noselect \HasChildren) "/" "mail/anotherfolder"
* LIST (\NoInferiors \UnMarked) "/" "mail/anotherfolder/mbox2"
8 OK List completed.

Now there is config setting in dovecot.conf called tb-extra-mailbox- 
sep. Maybe that is what the complaint is. Tbird will put the delimiter  
on the back end of the delete command(delete mail/anotherfolder/).

I have an older version of Uwash in use(2006k?) and folders with  
subfolders works. Maybe you are talking about folders that have  
messages and subfolders?
