Where you currently have "domains = +local_domains" on some number of
Routers, you should be able to instead have:

  condition = ${lookup mysql {SELECT DISTINCT user,domain FROM whatever \
                WHERE Enabled = 1 and domain='...' and user='...'}\
        {true}{false}}


Note that ${lookup...} takes optional extra parameters so that instead
of the $value from the actual lookup, you can use different results for
the match-found and no-match-found cases.

Alternatively, you can use a localpartlist with a name of your choice
and add a local_parts restriction to the Router(s).
