You can override the home dir returned by your userdb with a 
variable-expanded, "static" value by adding home to args[1].  You need 
to be careful and make sure that Dovecot doesn't use anything in the 
users' home dirs.  You may need to set mail_location and/or mail and 
create a virtual home-dir tree local to the Dovecot server.

Posting `dovecot -n` output would help.
