The way I personally prefer for small installations is....

- Use a directory /etc/exim/domains
- add one file per local domain

edit your local_domains to this
domainlist local_domains = localhost : dsearch;/etc/exim/domains

add a router like this one

virtual_aliases:
   driver = redirect
   domains = dsearch;/etc/exim/domains
   data = ${lookup {$local_part} lsearch* \
            {/etc/exim/domains/$domain}{$value}fail}


when every entry in your current virtuals maps to a system-account, then
make /etc/exim/domains/$domain look like this

*:catch_all_user
user1: domain1_user1
user2: domain2_user2

IMHO this is very easy to manage. But the final solution depends on your
needs ;)

No, it's not needed, exim opens the file when needed.
