You're right! I think unionmap is useful if there is a mix with mysql maps and pcre maps, or other mixed maps.
I modified my sender-login-maps.cf to include UNION with both of the queries. Thanks again, Viktor.

Congrats. I should perhaps note that with SQL you hardly need a unionmap: query = SELECT email as user FROM virtual_users WHERE email='%s' UNION SELECT owned as user FROM virtual_delegation WHERE owner='%s' -- Viktor.
