Hi Luca,
I do not see an option currently available which would allow delegated administrators to maintain the spam quarantine and SLBL for specific domains. It would be for the entire quarantine.
When creating a custom user role, you define the levels of access to the security features for which delegated administrators are responsible.
The security features available for delegated administrators to manage are:
• Incoming and outgoing mail policies and content filters.
• Data Loss Prevention (DLP) policies.
• Email reporting.
• Message Tracking.
• The Trace debugging tool.
• Spam, policy, virus, and outbreak quarantines.
• Cisco Email Encryption profiles.
After defining the access levels for a custom user role, you need to assign the specific mail policies, content filters, DLP policies, quarantines, or encryption profiles for which the delegated administrators will be responsible.
Thanks
