There are several ways you could go about this.
You could replace the setting of "file" by something like
file = "${if exists{/usr/exim/virtual/${domain}/aliases}\
{/usr/exim/virtual/${domain}/aliases}\
{/usr/exim/virtual/\
${if match{$domain}{^[^\\\\.]+(.*)\\$}{$1}{default}}/aliases}}"
That tests for the existence of /usr/exim/virtual/host.virtdomain.org/,
and falls back if it doesn't exist.
OR
Add the "optional" option to your director, so that non-existence of the
file just causes it to fail to handle the address, and add a second
director below it of the form
virtual_domains_default:
driver=aliasfile
domains=LOCAL
file=/usr/exim/virtual/${if match{$domain}{^[^\\.]+(.*)\$}{$1}{default}}/aliases
search_type=lsearch
(Note the different use of \\ because I haven't put that one in "".)
OR You could even put the name of the alias file for each domain as the
data in the list of domains, with lines like
*.virtdomain.org /usr/exim/virtual/virtdomain.com
and set file=${lookup{$domain}partial-lsearch{.... etc.
