During installation, you can add a folder to the server-side mailbox of each end user for Microsoft Exchange. You name the spam folder and configure the storage time limit during the installation process. Trend Micro recommends naming the spam folder "Spam Mail". When ScanMail detects spam messages, the system quarantines them in this folder according to spam filter rules predefined by ScanMail. End users can view this spam folder to open, read, or delete the suspect email messages.

End users can open email messages quarantined in the spam folder. When they open one of these messages, two buttons appear on the actual email message: Approved Sender and View Approved Sender List. When they click Approved Sender, ScanMail moves the message from that sender to their local Inbox, adds the address of the message to their personal Approved Sender List, and logs an entry of the event (the administrator can view this log in a report at a later time). Clicking View Approved Sender opens another screen that allows the end user to view and modify their list of approved senders by name or domain. When the Exchange server receives messages from the addresses on the end user’s approved sender list, it delivers them to the end user’s Inbox, regardless of the header or content of the message.

ScanMail also provides administrators with an Approved Senders and Blocked Senders list. ScanMail applies the administrator’s approved senders and blocked senders before considering the end user list.
