I have exim setup on a PowerMacG4 as our mail server. It works very well but I can't figure out where to send messages for unknown users. The messages bounce, but I want to be able to send the message to a valid user. eg. suppurt@my.company.com is a typo, so I would like to be sent to the sysadmin or someone else in the company. I'm sure there is a way to do it but I can't find it. Thanks for any help or pointers, Brendan Simon.
