[Exim] How to verify (with ACL) virtual domain accounts like…

Dear collegues,

I want to implent virtual domains like described in the docs, section 42.6
virtual:
    driver = redirect
    domains = dsearch;/etc/mail/virtual
    data = ${lookup{$local_part}lsearch{/etc/mail/virtual/$domain}}
    no_more

question is how to verify recipient address

does

deny domains = +local_domains
!verify = recipient/callout=10s, defer_ok, no_cache

still work?
what else ?
