I found in the logs, that the DNS lookup form the smarthost must be
reasonable for it. It looks up the sender Domain (virtual-domain.com)
that points of course to the ip of my root server, who is in reverse
host.my-domain.com. So how can i prevent it? Or better: how can i
ensure, that the senders address is always the account@????
