Well,I tried your second suggested change to exim.conf. Then I copied
/etc/aliases to /etc/aliases.domain2. Then I made a new alias in
/etc/aliases.domain2 that doesn't exist in /etc/aliases, but I got a
failed delivery:

SMTP error from remote mailer after RCPT TO:<xxx@???>:
     host 127.0.0.1 [127.0.0.1]: 550-Mailbox unknown.  Either there is 
no mailbox associated with this
     550-name or you do not have authorization to see it.
     550 5.1.1 User unknown


any help appreciated.
