qmail's structure make this exceedingly easy.

Add the domain in question to rcpthosts.  Add a loop-back entry for
the domain to smtproutes.  Add an entry for the domain to virtualhosts.
Create a maildir for the domain.  Create a .qmail-default entry for the
domain pointing to the maildir.  Use maildirsmtp to transfer all the
mail stored in the maildir to the remote domain over a single smtp
session.
