Hello 

We are using NBU 7.6.0.3 which is our master and media server same and backing up NDMP servers. Our Team has decided to configure email alerts for the ndmp backups and here are requirement mentioned below.

We have 4 departments and have 4 ndmp servers 1 for each department which gets backed up in 4 different policies.

For example ndmpserver1 is for r&d department then we need to send an email alert to r&d team head's email id.
