What does quarantine mean and how can I access it?

You have the possibility to access the quarantine area of your domain either via IMAP or via the web interface. Please note that the use of quarantine is only optional and not mandatory. Alternatively, you can also use the periodic user reports to check blocked messages and release them if necessary. More information can be found in our FAQ article "How can I be informed about blocked incoming messages?".

E-mails that have been quarantined are rejected with a 5xx SMTP error at the SMTP level. The sender will be informed of the rejection with a notification. Messages that are only temporarily rejected at SMTP level are not included in the quarantine and will be re-delivered by correctly configured sender servers. Messages that end up in quarantine are generally held for 14 days.

Access via Admin-Panel (Browser)

From the Admin Panel, you can either delete messages detected as spam from quarantine, block the sender, or release and train the message. In order to access from the Admin Panel, go to "Incoming" > "Spam quarantine".

If a message has been unintentionally blocked, you can release and train it at this point, which will trigger the message to be sent to the original recipient. In addition, a report of the incorrect classification is sent to our system along with a copy of the message to train our filter and improve spam detection.

Access via IMAP (Mailclient)

The quarantine system is supported by an IMAP backend. The backend can be reached via the administrator account, the domain (domain names) and the recipient's address. Customers can connect to the backend via the URL "quarantine. europeanmx. eu". Via IMAP you can also easily share certain messages in bulk. Further information can be found in our FAQ article "How do I have to configure my mail client (Outlook, Thunderbird, etc.) to access the quarantine via IMAP?".

There are certain special folders in the IMAP account:

• Caught

  ---

  All incoming messages that have been quarantined can be found in this folder. It is not necessary to report the messages as spam again, because they are already marked as spam. These messages are automatically removed.
  
• Caught (outgoing)
  

  ---

  All outgoing messages that have been quarantined can be found in this folder (optional). It is not necessary to report the messages as spam again because they have already been marked as spam. These messages are automatically removed.
  
• Training requested

  ---

  This is only relevant if a special feature has been enabled via the Software API or to store a copy of an unsafe message in this folder.
  
• Release & Train

  ---

  This is a folder that can only be written to (cannot be accessed via a mail client). E-mails that have been copied from the folder "Caught" by drag&drop are sent to the recipient and reported to our central system due to the incorrect classification.
  
• Release

  ---

  This is a folder that can only be written to (cannot be accessed via a mail client). Messages copied from the folder "Caught" by drag and drop are only delivered to the recipient.
  
• No Spam

  ---

  This is a folder that can only be written to (cannot be accessed via a mail client). E-mails that are copied from the folder "Caught" or "Training Requested" by drag&drop are reported to our central system due to the incorrect classification. The message will not be delivered to the recipient!
  
• Spam

  ---

  This is a folder that can only be written to (cannot be accessed via a mail client). E-mails that are copied to this folder by drag and drop are reported as spam to our central system (message is not delivered to the recipient). This is useful for reporting spam messages that have not been blocked correctly directly from the mail client to our system.
