SME Server Software Raid Failure, Grub 0x10 error

An SME customer called this morning saying that his system had apparently stopped working (web pages and mail were unavailable) and therefore he had rebooted.

SME Server Local Networks and VPN's

The SME Server (formerly E-Smith) normally rejects attempt to send mail outside of its own domain if you are connecting from somewhere other than the local lan. This is correct behaviour; otherwise anyone could use your server as a mail relay and you'd become an inadvertent spammer rather quickly.

SME Server (E-Smith) Mail Forwarding, Lists, Etc.

The Mitel Networks SME Server (formerly E-Smith)is a friendly web server and e-mail gateway. The original E-Smith is now called Mitel SME Server V5.
