Blacklist Senders Per User
- CASG allows admins to prevent certain senders from sending mail to specific users.
- This feature is useful in scenarios where you want to allow mails from a particular sender to all users in the domain but want to block the sender for a particular recipient in the domain.
- Senders can be added manually, imported from .csv and from a user request.

senders from a CSV file
Administrators can import multiple senders at a time from a comma separated values (CSV) file to sender blacklist per user.

Each line in the .csv file should contain the sender's email address and the username of the recipient or sender's email address and the recipient's email address, separated by a comma.
