This can't be done in Mailman without source code modification.

You would have to modify Mailman's SMTPDirect.py module to always set

deliveryfunc = verpdeliver

and then modify verpdeliver itself to look at the sender and recipient
and if the sender is local and the recipient remote, replace the From:

The mods would not be difficult nor extensive, but this can't be done
with configuration alone.
