It depends on how your MTA provides that information to the Local
Delivery Agent. That information may or may not be made available in
a header that is created by the local MTA, in which case Mailman
could look at that. But without support from your local MTA, there
is no other way that Mailman could know that information.

Some MTAs may encode that information in the "Sender:" header, yes.
