relay_domains matches all subdomains of the listed domains. This
is controlled with parent_domain_matches_subdomains. Unfortunately
the default value is a long list, so edit this carefully.
Perhaps using a regexp or pcre table for relay_domains gets rid of
this automatic subdimain matching behavior.
