OK, but I'm afraid I am not able to remember everybody's wishes in this
respect, expecially in the heat of answering n messages per day, so
forgive me if I don't always get it right. [There is a heated debate
raging on another list about the use of "Reply-To" in this regard.]

There is a strncmp() function in Exim, but I don't see how it helps at all.

Not if you set not_locally_caseless. You need an alias file for *all*
users, not just the caseful ones. It needn't polute the system aliases
file. Exim does allow you to have several different alias files. In
fact, you probably need to do something like
get_case_correct:
driver = smartuser
new_address = ${lookup{$lc:$local_part}dbm{/list/of/users}{$value}fail}
as your first director, with new_director set as well, to save it wasting time
doing it twice for each caseful local part.

Quite.

Exactly. The only sensible thing to do would be periodically to use the
functions for getting a complete list of users (getpwent() etc) and
build an "alias list" as described above.
