Sounds reasonable, as exim would see, that both addresses are redirected
to the same mailbox.

MTAs usually don't care much about the values of the To header field.
The Envelope-to header has most likely been added by your exim during
mail delivery, and also has nothing to do with mail routing in the first
place.

Well, the mail IS delivered to all recipients, isn't it? There's just
one (possibly) redundant copy missing. Exim removes duplicate addresses
from the list to which it is delivering, so as to deliver just one copy
to each address. I'm not sure whether it is possible to avoid that.

Hmm, exim (and any other reasonable MTA) generally DOES deliver every
mail to every envelope recipient, if it's able to. It does not by
default generate To header fields, allthough you can tell it to do, but
I don't think that relates to your problem.
