We have begun getting the message "Unauthorized origin ..." for mail being sent to owner-[listname], etc. Anyone know where I should start looking to see what has changed or where to fix this problem? A sample of the messages in the console log is below. 26 Mar 1996 13:07:13 Processing file 6997 from MAILER@UCBCMSA 26 Mar 1996 13:07:13 From [log in to unmask]: X-ADMMAIL OWNER-BACKUP-L ... 26 Mar 1996 13:07:13 Unauthorized origin - ignored.
