Spam Settings Explained

Spam Settings

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

Customize 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 [email protected] 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 endeavor to meet the needs of all users. It is possible to 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 the increment that is required to detect and manage modern sophisticated botnets. Spam sliders and adjustments of trigger levels are available per user and per organization. (The lower the trigger level, the more spam is stopped. The higher the trigger level, the less we stop spam.)

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

The following settings are available:

No – (Default Setting) Quarantine spam email. Deliver all others
All – Deliver all messages, but stamp spam email with the subject tag below.
Partial – Delivery non-spam email normally. Quarantine very spammy email. Deliver moderately spammy email stamped with the subject tag below.

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 explanation. 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

2 – A malformed MX record such as a record with a zero-length MX hostname

  • 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.
