If you intend to permit users to access Spam Quarantine, before you use Spam Quarantine, ensure that you have done all of the following:
Create and enable the spam policies that quarantine spam and suspected spam.
One or more policy groups must have an associated filter policy that quarantines messages. For example, you can create a spam policy that quarantines inbound suspected spam messages for the Default group.
Configure your LDAP server and ensure it works properly.
Control Center access to your LDAP server using authentication must work properly for users to logon to Spam Quarantine to check their quarantined messages. You also need LDAP authentication to expand LDAP email aliases and for the Delete Unresolved Email setting.
Ensure that you have an SMTP mail server available.
Spam Quarantine does not require a separate SMTP mail server to send notifications and resend misidentified messages. However, an SMTP mail server must be available to receive notifications and the misidentified messages that Spam Quarantine sends. The SMTP server that you choose should be downstream from the Scanner, as notifications and misidentified messages do not require filtering.
