By default, both envelope addresses and message sender addresses are shown in the quarantine list on the End User Console and in the quarantine digest notifications. Each envelope address is followed by the corresponding message header address in parentheses, in the format Envelope@example.com (Header@example.com).
For incoming email messages quarantined for a specific reason, you can choose to let end users view them and take action on the End User Console and in the quarantine digest notifications. Quarantined outgoing messages are always invisible to end users.
