Yes. If you wish, each email address (including aliases) will be quarantined individually to allow controlled custom settings for the specific email address (or alias). This is setup automatically by the service and requires no additional work on behalf of the Domain Manager. However, if you do not want individual quarantined mailboxes for all users, ALL quarantined email can be sent to a single mailbox specified by the Domain Manager upon sign-up. This way, the Domain Manager is responsible for sifting through quarantined messages.
