Think along the lines of reusing the existing dovecot code for mangling 
usernames into mailbox names:

  default_mail_env = maildir:/var/mail/%Lu/%u/Maildir

would be something like this to strip the domain:

  auth_passdb = passwd uname=%Ln

So not only does it use already existing dovecot code to process 
usernames, it also uses existing dovecot syntax, existing dovecot 
modifiers and does it in a generic way totally consistent with existing 
dovecot behavior.
