Hi All,


We have 1 Exchange Server here, which handles all the Internet e-mail coming into our company.  If that server goes down, can we recover all the missing Internet e-mails in any sent to us?  Can the ISP's DNS MX records be somehow used for this purpose?


Thanks,

Theo

you could setup the following on your mx records

mx priority 10 = (the ip address of your own mail server
mx priority 50 = the ip address of ISP server that hosts your domain name.
when your server is off line it will collect your mail , when yours is back up pull it down using a pop3 connector

Yes, you can add the ISP's mail server as an additional MX record with a lower preference (i.e. larger 'cost' or 'priority' number).

However, this approach is plagued with problems; most notably you have to use a POP3 connector to get the mail from the ISP down to your Exchange Server when connection is restored. Perhaps a better approach is to use an MX store-and-forward service, such as this one: http://www.no-ip.com/services/managed_mail/backup_mail.html. You point an MX record with less preference to No-IP's servers, who will store your mail - and, the best part of it - when your server comes back online, No-IP automatically forward the mail on to the server and deliver it just as if it was being delivered normally.
