Tom
that's very interesting info. Maybe someone has a manual or best way for
having a backup mx with qmail+vpopmail?
it would be great to add this to the toaster in an optional part (configure
a backup MX).

If the domain is only in rcpthosts, then your backup will queue it and
continue trying to deliver to the primary server.
If you have it in virtualdomains, then qmail should deliver it locally to
that machine. Of course, you need to figure out how to keep mail and
configuration information synchronized between the servers if you go that
route.
