Make the "another-list" list anonymous. Then the From: address in the
message it sends back to the tracking system will be the address of
the list which can be a registered user in the tracking system. The
original submitter is still available in the From: header of the
attached message.

Alternatively, if you can make the tracking system validate on envelope
sender, you only need to register
another-list-bounces at domainofmine.net as a user in the tracking
system. Note that if you can do this, you might also be able to have
the rejected-as-unknown mail go directly back to the tracking system
depending on what the envelope sender of the rejected-as-unknown mail
is.
