For the record, I was not using /./ in the home directory. For this user 
the home directory (and maildir) is /var/mailstore/af/4f/510590. While 
that may be a good thing, that deliver fails to create a user's maildir 
is a big problem for me, as I will have to actively provision maildirs 
for all new accounts before they can receive mail (or be converted)... 
so for the record, can I no longer count on dovecot to create user 
directories that don't exist?

All I'm dealing with here is mail. I'm converting from CommuniGate 
mailboxes to dovecot, so the whole concept of a home directory is just a 
technicality. In fact, I was initially just setting users' home to '' 
and using the mail_location setting to generate the path. The only 
reason I went back to setting home is because convert seems to create 
it's lock file in the home dir (so lock creation was failing trying to 
open /.temp...).  Here is what I'm feeding to convert:

convert_mail = 

And an example of the user's home/maildir:

mail_location = maildir:%h:INDEX=/var/indexes/%2Mi/%2.2Mi/%i

The index location here would be /var/indexes/af/4f/510590 (local disk).

One of the source hacks I've made for the CommuniGate format was setting 
a mask of *.mbox rather than just * when calling the 
mail_storage_mailbox_list_init functions... I didn't think that could 
cause a problem like this though. I also strip off the .mbox extension, 
and any occurance of .folder in the dest_name string in 
mailbox_name_convert(). All of that works perfectly so far in my 
testing, though, as long as the user's home directory already exists :)
