Filter Settings

March 14, 2024

In this page you can enable/disable your quarantine and manage your quarantine filter settings for incoming emails.

Important - If you choose to disable your quarantine, all emails detected as Spam will be delivered to your email server unfiltered.

In the Domain Level Control Panel, select Incoming - Protection Settings > Filter settings.

The Filter settings page for your domain is displayed:

Filter Settings | Picture 1
Setting Description
Manage list of domains and IP addresses with disabled SPF, DKIM, and DMARC checks This link opens a page which allows you to disable SPF, DKIM and DMARC checks for specific domains, IPs or subnets - so that if, for example, an SPF check fails for any of the specified domains or sender IPs, the system will continue to process the message.
Quarantine enabled

Enables/disables the quarantine.

Important - If you choose to disable your quarantine, all emails detected as Spam will be delivered to your email server unfiltered.
Quarantine threshold

Messages in Spam Experts that have a combined score above this setting will be classed as spam and will be handled as spam. If this quarantine threshold setting is lowered from the default (recommended) value, more messages will be seen as spam.

If this setting is increased towards 1.0, fewer messages will be handled as spam and so the potential for spam to be delivered is much higher.

We do not recommend making any changes to this setting. Any changes should be small, either increasing the aggressiveness of the filter by setting a lower numeric value closer to 0.0 or lowering the aggressiveness by setting a value closer to 1.0.
Beneficial to train threshold

Messages in Spam Experts which have a combined score between the Beneficial to train threshold and the Quarantine threshold will be considered "unsure" to the filter. A Beneficial to train notation is available, to prepend the subject line of messages receiving this classification (as a warning that this message scored above the threshold which mail is considered to be good mail or "Ham"). This setting is used to tag messages with a specific notation, which are considered suspicious to the filter but not suspicious enough to be treated as spam. All messages with a score below this threshold will be delivered.
Sender checks
  • SPF (Sender Policy Framework) - This is a common check that allows the sending domain administrator to indicate which IPs are allowed to deliver email for their domain. We advise keeping this enabled to block Spam.
  • DKIM (DomainKeys Identified Mail) - This allows the sending server of a message to cryptographically sign fields of the message to ensure its integrity upon its receipt.
  • DMARC (Domain-based Message Authentication, Reporting & Conformance) - An email authentication system that adds to SPF and DKIM by also checking the header From address for SPF validation and ensuring that the From address and DKIM signature domain are aligned with the SMTP From domain. This also includes a reporting function that allows senders and recipients to improve protection of the domain from fraudulent email sources.
Skip maximum line length check There are strict regulations on allowed line length in emails which are automatically enforced by the email software. Some applications or badly developed scripts do not adhere to the official specifications thereby exceeding the maximum allowed line length. This check can be disabled by ticking this box but we advise keeping it enabled to block Spam.
Reject messages from newly registered domains If set, then any message sent from a domain that is newly registered (less than a day) will be rejected
Beneficial to train notation Text added here is prepended to the subject line of all messages classed as unsure.

Quarantine response

When an incoming message is detected as spam and quarantined, the response you send to the Sender can be Rejected or Accepted.

  • Accepted: the message will be quarantined and the sender will not get a bounce message.

  • Rejected: the message will be quarantined and the sender will get an NDR.

The default and advised setting for incoming mail is 'Rejected'.
Require TLS Settings

By default, all email is securely processed using TLS encryption as long as the sending/receiving server provides support for it.

Using these settings, you can specify that TLS is compulsory for specific senders/recipients; if a TLS connection is unsuccessful the email will not be processed and delivered.
