I need someone to configure a backup mail server and secondary dns server using a UML VPS (I already have an provider).

1. backup mail server
- will store my clients email when primary server is down and forward to my primary server when back online.

2. secondary dns server
- this will allow to host my dns server when primary server is down.

3. will teach me how to use the features (in case need to setup domain name or email account in VPS.

Please PM me for details. Expecting reasonable price.
