If your configuration is anything like the default, then you should have
a "local_delivery" transport which looks like:
local_delivery:
driver = appendfile
file = /var/mail/$local_part
delivery_date_add
envelope_to_add
return_path_add
group = exim
user = $local_part
mode = 0660
no_mode_fail_narrower
This is the mechanism invoked by the "localuser" Router for
"transport"ing the mail to its destination.
Change the "file = ..." line to be constructed differently:
file = ${lookup {$local_part}lsearch{/my/special/file}}
That assumes that every user is always listed. If some users aren't
listed and you want those users to default to /local/mail/ then:
file = ${lookup {$local_part}lsearch{/my/special/file}{$value}{/local/mail/$local_part}}
Exim comes with a file "spec.txt" which the full doc; it's also
browsable online at
www.exim.org; see:
9.3 Single-key lookup types
and other areas around here for more information on the types of
lookup that can be done and how to allow forms of wildcarding, etc.

${lookup{<key>} <search type> {<file>} {<string1>} {<string2>}}
