Good idea, vilic! Since the device has changed from ASG to UTM and soon to SG, I've used secure.company.com recently where there already was a "mail" member of AD, and haven't changed the banner in 'Advanced'. The key in both our approaches is that the primary MX record for the domain is for an FQDN that points at the IP of "External (Address)."
