Look up the "prefix" and "suffix" options of directors. A smartuser
director with options along the lines of
suffix = +extension
new_address = some kind of lookup to get the rewrite, and then
manipulation involving the use of $local_part_suffix
to put the extension back. Depending on your lookup,
could be messy...
might do the trick.
