Recipient Email Mailing List Aliases and Spam Notifications

Notifications can be sent to each Envelope Recipient that has quarantined email, including mailing lists and other aliases. Each mailing list receives a single digest. If you send notifications to a mailing list, all subscribers to the list will receive the notification. Users who belong to multiple email aliases, or who belong to LDAP groups that receive notifications, or who use several email addresses, may receive multiple spam notifications. The following table shows example situations in which users may receive multiple notifications.

If you use LDAP authentication, you can choose not to send notifications to mailing list aliases. Or, if you choose to send spam notifications to mailing list aliases, you can prevent some occurrences of multiple notifications. .

Users who access the spam quarantine by clicking a link in a notification will not see quarantined messages for any other aliases that the end-user may have, unless the appliance is using a spam quarantine alias consolidation query for email notifications. If the notification was sent to a distribution list that is expanded after processing by the appliance, then multiple recipients may have access to the same quarantine for that list.

This means that all subscribers to a mailing list will receive the notification and can log in to the quarantine to release or delete messages. In this case, end users visiting the quarantine to view messages mentioned in a notification may find that those messages have already been deleted by other users.

Note
If you do not use LDAP and you do not want your end users to receive multiple email notifications, consider disabling notifications and instead allow end users to access the quarantine directly and authenticate via LDAP or POP/IMAP.
