Forgot that Postfix is hard-coded to append @$myhostname.
In that case, you'd have to use canonical_maps to rewrrite
double_bounce@$myhostname:
canonical_maps = inline:{$double_bounce_sender@$myhostname=somethingelse}
(assumes Postfix 3.x). Having the map inlined in main.cf brings the
benefit of parameter expansion.
