http://forum.civicrm.org/?topic=11322 - with the new reply handling in CiviCRM 3.0, the From: email address of the forwarded reply is being reset to the CiviMail's address (rather than being the address of the replier).
This is most probably due to the code path with $fullEmail set not setting From: properly in CRM_Mailing_Event_BAO_Reply::send().
