Spam Quarantine

The incoming Spam quarantine holds incoming messages that the filtering system rejects with a 5xx SMTP rejection code at SMTP level. Legitimate sending servers inform the sender about the rejection.

By default, the quarantined spam is stored for 14 days. Spam messages that were temporarily rejected at SMTP level are not listed in the quarantine, and will be automatically retried by legitimate sending servers.

What do you want to do?

Enable the Quarantine

Enabling the quarantine is optional, but you must enable it for it to start rejecting messages and for you to view those messages:

In the Domain Level Control Panel, select Incoming - Protection Settings > Filter Settings and ensure the Quarantine enabled box is ticked:

IMAP Access

The quarantine system is powered by an IMAP backend. The backend is accessible as super-administrator (using the special "global" account), domain (using the domainname), and recipient (using the email address). Customers using the Spam Experts hosted cloud can connect to quarantine.antispamcloud.com.

Users on a Spam Experts Local Cloud can use the hostname of the primary server in that cluster (or a CNAME associated with it). We have instructions available for Thunderbird and Outlook. Using IMAP you can also apply mass actions to specific emails by dragging to specific folders.

For Local Cloud users there is also a special "global" account which can be used to retrieve IMAP access to all quarantined messages. This is for super administrators only.

IMAP folders

There are several special folders in the IMAP account:

  • Caught: All incoming messages which have been quarantined can be found in this folder. It's not necessary to report these emails as Spam again, as they have already been classified as such. These emails will automatically expire.
  • Caught (Outgoing): All outgoing messages which have been quarantined can be found in this folder (optional). It's not necessary to report these emails as Spam again, as they have already been classified as such. These emails will automatically expire.
  • Training Requested: This is only relevant if a special option as been activated via the Software API to store a copy of unsure classifications in this folder. These messages have been delivered, but can be manually dragged/dropped to "Not Spam" or "Spam" to further fine-tune the systems. Please contact support@spamexperts.com if you would like more information on this one.
  • Release & Train: This is a write-only folder (which cannot be accessed by the email client). Emails drag/dropped from "Caught" to this folder will be delivered to the recipient and reported as a classification mistake to our central systems
  • Release: This is a write-only folder (which cannot be accessed by the email client). Emails drag/dropped from "Caught" to this folder will be delivered to the recipient only.
  • Not Spam: This is a write-only folder (which cannot be accessed by the email client). Emails drag/dropped from "Caught" or "Training Requested" to this folder will be reported as a classification mistake to our central systems (it will not be delivered to the recipient)
  • Spam: This is a write-only folder (which cannot be accessed by the email client). Emails drag/dropped to this folder will be reported as a Spam to our central systems (it will not be delivered to the recipient). This is useful to report spam which was not blocked correctly directly from the email client.
