I've used the technique described at
http://www.exim.org/exim-html-4.20/doc/html/spec_41.html#SECT41.6
virtual:
driver = redirect
domains = dsearch;/etc/mail/virtual
data = ${lookup{$local_part}lsearch{/etc/mail/virtual/$domain}}
no_more
It's really very powerful, yet simple. First The directory
/etc/mail/virtual is checked for a file with your virtual domain
name. If found, that file is consulted for further aliases. You
don't maintain one single file for all domains but one for each
virtual domain.
You even can use the dsearch construct in other places where you
need to check whether you're responsible for a given domain. This
reduces the work to create a new virtual domain by just creating an
empty file in the directory /etc/mail/virtual and/or enter any
further aliases you need.
