Create a file that lists your domains and their destinations. Mine is
called 'CONFDIR/domain-aliases'. This assumes that user X has email
address x@localdomain.

*.mydomain.com    x@localdomain

If you need to construct a domainlist from this file, for use in ACLs or
elsewhere, you can use:

domainlist xyz_domains = partial-lsearch;CONFDIR/domain-aliases

Then put this in your Exim config:

# Router for forwarding mail for certain (sub)domains to a single address
subdomain_route:
         driver                  = redirect
         data                    = 
${lookup{$domain}partial-lsearch{CONFDIR/domain-aliases}{$value}fail}

Best regards,
