put the domain name in /var/qmail/control/rcpthosts
e.g.
if the DNS has:
mail.example.com IN MX 10 primary.example.com.
IN MX 20 secondary.example.net.
then rcpthosts on secondary.example.net. needs a line:
mail.example.com
so it knows to accpt mail for that domain. As it is not in 'locals' qmail
qill then know that it needs to forward mail using SMTP.
