Having just gone through this, I think I know your answer. There are various flavors of Maildir, the one that dovecot uses has . (period) as the separator between levels. I had to tell my MUA to use "." rather than "/" as the separator and everything worked on that end. Also, when adding things by hand, all the folders live directly under ~/Maildir (or where ever you set it) and each level of hierarchy is preceded with a "." So if you want to have a tree with test/junk, test/junk/more, test/misc, you would see .test.junk, .test.junk.more and .test.misc in the Maildir directory, each containing cur, new and tmp directories. Note that if you don't store mail in test/junk, the directory .test.junk would not exist.
For Gregory, you needed to change the hierarchy separator for the IMAP account in Mulberry to get it to work.
hope this helps. jerry

Thank you. I knew about prefixing with a dot, but I still had my slashes. Here was my procmail filter before:
.Lists/.dovecot/
But when I put it to this:
.Lists.dovecot/
It works. I knew it was something simple. I also now understand something I saw on a mailing list about dovecot not actually creating folders in a traditional hierchy sense, but rather all in the top level. Thanks again.
