Sweet!

Do you mean folders don't have to start with a dot?  I started to  
propose that too, but thought I'd be asking for too much.

Specifically, there is a bit in the config:

# By default LIST command returns all entries in maildir beginning  
with a dot.
# Enabling this option makes Dovecot return only entries which are  
directories.
# This is done by stat()ing each entry, so it causes more disk I/O.
# (For systems setting struct dirent->d_type, this check is free and  
it's
# done always regardless of this setting)
maildir_stat_dirs = no

So it seems that removing the dot would break that unless cur/tmp/new/ 
subscriptions/dovecot* started with a dot and folders did not (thus  
reversing the usual convention).  It seemed too much to ask for for  
too little gain, especially as maildrop wouldn't know how to deliver  
to such directories (but maybe it could call deliver).

So what happens if I use the following two together, on a system not  
setting struct dirent->d_type?

mail_location = maildir:~/Maildir:LAYOUT=FS
maildir_stat_dirs = no

Since I have no idea what that actually means, is linux one of the  
systems that does set struct dirent->d_type (JFS filesystem if it  
matters)?

Lastly, any idea how long before this feature can be expected to  
reach production?
