Note that you are JOINing "domain d" with "account_info a"; by the time
this is looked up, there is no relation co there, so the qualification
doesn't make sense. Try this:
SELECT co.first_name, co.last_name, co.email_address,
a.password, c.company_number
FROM domain d, contact co
LEFT JOIN account_info a ON (co.contact_id = a.contact_id)
LEFT JOIN company c ON (co.company_id = c.company_id)
WHERE d.domain_id = '666'
AND d.company_id = co.company_id;
