You need two routers; first a virtual-alias router that looks up in
aliases.$domain, and then the system alias router that looks up in aliases.
The typical way to to the first router is a directory (such as
/etc/exim/virtual) containing only alias files named after the domain,
so you can use dsearch in the domains condition and don't need the
exists check in data.
Here's my router:
# Route mail to our virtual hosts: each host defines an aliases file
# in the /etc/exim4/virtual directory.
virtual:
debug_print = "R: virtual for $local_part@$domain"
driver = redirect
domains = dsearch;/etc/exim4/virtual
data = ${lookup{$local_part}lsearch{/etc/exim4/virtual/$domain}}
