The Quarantine Viewer lets you see messages which have been quarantined by the VPOP3 Spam Filter. As an administrator you can see quarantined messages for any user, and release them if appropriate. If you release a message, it will be sent into the original recipient's Inbox, not into your Inbox.
The Quarantine Viewer will not display any messages when you first view the page, you must first select criteria and then press the Go button to view the selected messages.
You can choose to view messages based on received date, time, user (original recipient), sender, subject and maximum size. The Sender and Subject searches are simple substring searches, you can't use wildcards or regular expressions.
Once you have selected the search criteria, press the Go button and VPOP3 will display the quarantined messages which match the search.
When the search results are displayed, you can double-click on a message to view the message headers & source. If you wish, you can Release the message to have VPOP3 send the message to the original recipient.
There are some options which you can choose when releasing the message:
When the search results are displayed, you can click, shift-click & ctrl-click on messages to select multiple messages, then press the Release Msgs button above the results list to release all the selected messages. VPOP3 will just train the Bayesian spam filter component that these messages are not spam. The other options which are available on individual message releases are not possible here.
However, some people like to manage the list further, so there are two options which can be used:
You can click, shift-click & ctrl-click messages to select multiple messages before hiding or marking messages as seen. If you select hidden or 'seen' messages, then you can choose to unhide or mark them unseen.
These options merely control the display of the quarantined messages, not how long they are kept, or any other behaviour.
