> Chet If both of your nameservers are offline remote mail servers are likely to start bouncing mail back to the sender because an MX lookup reveals nothing. If the remote server can find a record it should queue the message for a period of X hours/days and retry delivery. Ideally you should have at least one nameserver and one backup MX outside your main network so that mail is delayed rather than lost. If you only have an 'external' nameserver you rely on the configuration of the remote server to queue mail - hence the need for an 'external' mail server. -Nathan Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
