Yes, bmx.01.com is our backup mail exchange (mx) server.

10 mx.01.com
20 mx-a.01.com
30 bmx.01.com

Note that while mail stored on bmx.01.com is not viewable to clients, bmx.01.com will queue and forward mail for our clients' domains in the event the destination server is unreachable, such as during scheduled maintenance (clients, please see our help desk News for our maintenance schedule). Also, bmx.01.com will queue messages for up to 5 days in the event of a disaster.

Please note that when you place your order, your chosen domain is configured automatically on the 01.com servers.  Mail will not be directed to your domain on the 01.com servers until you change your MX record in your DNS.  The exception to this rule is for existing clients using the 01.com servers, including 01.com team members: for these users, the 01.com mail server will attempt delivery only to the domain installed locally.  For example, prior to switching your MX record, if you're wondering why you haven't received responses from 01.com team members, check your mailbox on the 01.com server, because our messages, sent through the 01.com servers, will be delivered there.
