SMG allows administrator to deligate release of email from spam quarantine to individual users via user spam quarantine access. This is a very good feature for large organizations. However there is a limiation to this feature in terms of the fact that this access is granted only for inbound spam.
It is deisred to allow access for outbound spam as well. There can be a consilidated access to both inbound and outbound spam for individual users with ability to allow either only inbound or outbound or both at the group level.
