Indeed, because that is the way the passwd file is organized. I can't
offhand think of a way of doing this directly in Exim. What you can do
is pipe undeliverable messages off to a script or program which can then
do its own searching and possibly re-inject the messages if it likes
them. Of course, this requires you to accept all local parts, which may
not be the best plan.
It would be necessary to write a new search type to do the kind of
searching you are suggesting. You would also want to be sure that only
*one* record in the file matched. What if you have
ph10:x:100:100:Philip Hazel:/home/ph10:/bin/bash
ph11:x:200:200:Paul Hazel:/home/ph11:/bin/bash
and somebody mails to P.Hazel? (I'm just pointing out some of the
dangers in this kind of thing.)
