Quarantine mailbox and MS Exchange quarantine
If you decide not to use Local quarantine you have two options, either Quarantine mailbox or MS Exchange quarantine. Whichever option you choose, you need to create dedicated user with a mailbox (for example, firstname.lastname@example.org) which will then be used to store quarantined email messages. This user and mailbox will also be used by Mail Quarantine manager to view and manage items in the quarantine. You will need to specify account details of this user in Quarantine manager settings.
When comparing Quarantine mailbox and MS Exchange quarantine, both options use a dedicated mailbox as an underlying mechanism for storing quarantined messages, but they differ slightly in the way how email messages are delivered to the mailbox. Quarantine mailbox vs MS Exchange quarantine:
•If you choose Quarantine mailbox, ESET Mail Security creates a separate wrapper email with additional information and the original emails as an attachment and delivers it to the mailbox.
•If you choose MS Exchange quarantine, Exchange Server is responsible for delivering the email to the mailbox itself. The mailbox must be set as a Quarantine at the organization level in the Active Directory (by a PowerShell command listed below).
•MS Exchange quarantine - ESET Mail Security uses Microsoft Exchange quarantine system (this applies to Microsoft Exchange Server 2007 and newer). In this case, the Exchange's internal mechanism is used to store potentially infected messages and SPAM.
•Quarantine mailbox - Specify message quarantine address (for example, email@example.com).
