I've got a domain ( registered with Google Apps, and have their mailservers registered as the MX record for my domain. I also have a site with a central mailserver (Exim4 on Ubuntu), and a number of other servers. Each server is set to use this mailserver as a smarthost for outgoing mail.

The issue I have is that when a server sends mail to an address of the format (e.g. when a cronjob fails), the mailserver doesn't know what to do with it. It tries to make an SMTP connection directly to, which fails.

How would I configure exim so that it knows to deliver @* to the MX record for

Or configure your various servers to send mail from * instead of *
