If it's a manually maintainable list (ie, not hundreds or so of users -
something you can maintain by hand), you could quite simply have the Exim
system query a file that would contain the smtp system IP that Exim should
route the email to (ie, query user@??? and retrieve back an IP that
it uses as the remote SMTP system to deliver to). This would be relatively
simple to implement - would just be a new router and/or transport and a db
file of the routing list (in fact, you could even make it so that if no
entry was returned, it defaults to your old Sendmail system - thus your list
would only have to contain Zimbra users).
