Hi All, Someone knows how i can set exim to when a e-mail arrives for a unknow user its transfer to a mailbox of a know user. I try to put lsearch* in exim.conf and *: userknow in the aliases file. But all e-mails comes its tranfer to this userknow!! I want to transfer only the unknow users to this user to the all. Tanks a lot. Alberto Pereira
