Spam Settings Explained

Spam Settings

Spam settings can be adjusted from the Spam options tab when logged into your interface.

Customise Spam Filtering

Some users might need different spam filter levels, filtering turned forward only, or to manage their own filter settings.

Spam filter levels

Most users probably want all categories of spam filtered aggressively. Your Sales team, however, might want lenient filtering of Commercial Offers, so potential leads aren’t wrongly identified as spam. You might place in an account where the spam slider is adjusted to a less aggressive trigger point

Spam Slider

This feature has a wide range of setting (2 - 22) which endeavour to meet the needs of all users. It is possible manage your users Spam trigger threshold by adjusting this slider to a trigger level more closely to their needs. The range includes:

  • Very Strict: 2 - 3
  • Strict: 4 - 5
  • Standard: 6 - 8
  • Loose: 9 - 14
  • Very Loose: 15 - 22

Within each of these ranges is a fine tuning range to keep detection in as small steps of increment that is required to detect and manage modern sophisticated botnets. Spam sliders and adjustments of trigger levels are available per user and Per organisation. (The lower the trigger level, the more spam is stopped. The higher the trigger level, the less we stop spam.)

Quarantine Bulk Email

Where the setting is found:

Go to Company Settings > Spam > Quarantine bulk email

What the setting does:

Quarantine bulk email will quarantine emails if they are scanned and are identified as “Confirmed Bulk Email” based on numerous factors also of your spam sensitivity level.

How It functions:

When an Inbound mail arrives, and the spam setting “Quarantine bulk email” is checked. We scan the email and add additional bulk factors to the email if found to be a “Bulk” email.

Depending on your Spam Sensitivity Trigger Level if the email is “Confirmed Bulk Email”, this will add factors. If the overall results over your trigger level, it will be quarantined. If the overall results below your trigger level, It will not be quarantined.

Spam filtering on/Stamp & Forward

Most users want their spam filters on. But they might want to forward spam that through to Customer Support for further analysis. So that potential spam can get through, you can choose
Stamp & Forward for the email addresses used by Customer Support.

Include an easy-spam-reporting disclaimer in passed email:

After you have set the disclaimer you can set this option by checking the box as described here.

Update spam detection settings above for all existing user accounts:

This feature will retroactively activate the above features across all users (regardless of their personal settings currently set).

Inbound Sender DNS sanity checks (disable at own risk):

Please review this article for a more detailed explaination. When enabled, the “Inbound sender DNS sanity checks”  provides an additional validation on the sender domain DNS on Inbound Email. The validation includes:

  1. Sender Domain MX Records
    • A message will be rejected if "the MAIL FROM domain has:
      • No DNS A or MX record, or
      • A malformed MX record such as a record with a zero-length MX hostname
  2. Sender Domain MX Records that point to private / reserved IP ranges
    • This signals a severe DNS misconfiguration and as a result we would reject the message.
