Explanation

When Cisco ESA's spam quarantine uses mailbox authentication (LDAP or Active Directory) to verify user identity before granting access, it authenticates users against their actual mailbox credentials. An email alias is not a real mailbox - it has no associated password or directory account of its own. Therefore, a user cannot authenticate using the alias itself to view quarantined messages addressed to that alias. Mailbox authentication relies on a valid, authenticatable account, which an alias does not provide. Access to alias-addressed quarantined messages is only practical via a quarantine notification link (A), which bypasses direct authentication by using a time-limited token in the notification email.
