Rackspace Broke my Email Settings

I formerly used my Rackspace email to send messages from the PBX, namely voicemails. I used authentication and TLS. Rackspace now requires an A or MX Record for the hostname on the PBX. I have no intention of attaching those to my PBX, which sits isolated from the Internet.

What’s the best way to configure this to get it working again?

Obviously not, as it can send email.

Just add an A record of bob.domain.com pointing to whatever IP your PBX’s public traffic comes from.
