You can't use the $domain directly to construct a file system path.
See the "tainted" wording:
> 31068 LOG: MAIN PANIC
> 31068 Tainted filename for search: '/etc/exim/aliases.d/DOMAIN001.COM'
> 31068 system_aliases router: defer for support@???

The $domain is data we do not have under control.
You need another lookup first, to check if the $domain matches your
expectations, and then use "$domain_data", which will be untainted.
system_aliases:
…
domains = +local_domains
data = ${lookup{$local_part}lsearch*@{/etc/exim4/aliases.d/$domain_data}}
