That is not enough, because after john has been turned into johnny, it
will be re-evaluated and will hit the first line.

Actually, that won't work anyway, because you have a mixture of keys,
some including a domain and some not. You'll either need to use two
routers, or adjust the new addresses.

You can stop the re-aliasing happening be setting the redirect_router
option on the router to tell Exim where to start routing the new
address. An alternative would be to block mail to johnny at SMTP time
using an ACL.

Yes, in a number of ways, some involving the "unseen" option, and some
involving the system filter.

Ah. In that case, a lot of what I said above doesn't make too much
sense, because it applies to Exim 4. However, some of the facilities
were available in Exim 3, but in different ways.

Sorry, I'm rapidly forgetting how to do things on Exim 3, since Exim
4 has been out for nearly a year now.
