Messages you submit to the newsgroup are forwarded to the mailing list.
When mail messages bounce, the MTA (Message Transfer Agent--the program
that handles mail) *should* send the bounce message to whatever is in
the Sender header, and only if that header does not exist, should it
use the From header.  Messages forwarded by the gateway get a Sender
header which points back to the gateway.  In other words, if a message
gets bounced back to the From address, the MTA does it incorrectly.
There is nothing the list administrator can do about it.  You can try
complaining to the postmaster of the bouncing system, but that's about it.

In other words, your question in the first paragraph is already
implemented and was implemented from the beginning.  It is not the
gateway's fault that there are systems that don't follow the standards.
