The exim 4 config is very similar to do this. The best way to do it,
IMO, is to reorganize your configs so that you have a directory
/etc/exim/config/domains/ , and within that dir, you have a file whose
name is the domain name, containing the user names. You don't need the
local.domains file, because that can be determined using dsearch from
the domains directory contents.

Your transport simplifies to:

maildir_delivery:
driver = appendfile
maildir_format
delivery_date_add
envelope_to_add
return_path_add

Your director becomes a router:

maildir_local:
driver = redirect
domains = dsearch;/etc/exim/config/domains
local_parts = /etc/exim/config/domains/$domain
check_local_user
data = $home/Maildir/
directory_transport = maildir_delivery
