We have a similar path structure. It is hard to tell from your post what is 
wrong but since you are upgrading I'll take a stab at it. In version 1.0rc12 
the default_mail_env configuration was renamed to mail_location, for example, 
this is an excerpt from our config and my iterative changes... the %L forces 
lowercase

#--JIM renamed mail_location in rc12
#default_mail_env = maildir:/home/services/mail/%d/%n/Maildir
mail_location = maildir:/home/services/mail/%Ld/%Ln/Maildir

HTH,

Jim
