Spam Filtering

SmarterMail includes a variety of antispam measures that will help keep a user's inbox free of unwanted mail. In the Spam Filtering section, users can review/configure the spam filtering options and trusted senders for their account. To access the spam filtering configuration, log into SmarterMail and use the Menu icon to navigate to the Settings section. Then click on Spam Filtering in the navigation pane.

In most cases, a System or Domain Administrator has already configured the filtering options for spam messages on your domain. However, if they allow it, you can override those settings to select your own options for filtering out potentially unwanted email.

Options

  • Override spam settings for this account - Enable this setting to customize the way spam is handled and to override the settings created by the Domain Administrator. If this option is disabled, the domain's default spam filtering policy will be displayed and cannot be edited.

When you override the spam options set by your Administrator, you can choose the actions that are taken when email comes in that has a low, medium, or high probability of being spam. For each spam level, choose the action you wish to have taken. If you choose to add text to the subject line of messages, type the text in the box below the action drop down.

Trusted Senders

Users can add specific email addresses (such as jsmith@example.com) or domains (such as example.com) that will be exempted from spam filtering. This lets the system know that these messages come from a trusted source and can prevent mail from friends, business associates and mailing lists from being blocked or sent to the Junk Email folder. By default, every contact in a user's Contacts list is considered a trusted sender and bypasses spam filtering.

Note: If SPF and DKIM spam checks are enabled, SmarterMail will run those checks on ALL emails, including those from trusted senders. Because anyone can write any return path that they want when sending a message, this extra check helps prevent spammers from flooding users with hundreds of messages that aren't truly from a trusted sender. If the SPF and DKIM weights on a message from a trusted sender meet the Low, Medium or High spam filtering threshold, the corresponding spam filtering action (Move to Junk Email Folder, Delete Message, Add Text to Subject) will be performed on that email, despite the email coming from a trusted sender.

When entering trusted senders or domains, enter only one item per line break.

Blocked Senders

Users can add specific accounts to their Blocked Senders list. For example, if you receive a message from dan@im-a-spammer.com, you can left click on the email address in the message view and select "Block Sender" from the context menu. When you do this, that message, and any future message from that specific sender, will have whatever Action is set on the Blocked Senders card applied. This allows users to have a bit more granular control over senders that escape whatever spam filtering the system administrator has set up. NOTE: Any Action set on the Blocked Senders card are applied just for the user who sets them -- these Actions are not domain-wide or system-wide, they are only applied for the specific user who creates them.

As for the Actions themselves, they include:

  • None - Nothing happens to the messages from Blocked Senders.
  • Move To Junk Email Folder - Messages are moved to the Junk folder, then handled however items in that folder are handled. (E.g., auto-clean rules.)
  • Move To Deleted Items Folder - Messages are moved to the Deleted Items folder, then handled by whatever rules apply for that folder. (E.g., auto-clean rules.)
  • Delete - The messages are flat out deleted and, therefore, unrecoverable.

Any address that has been marked for blocking will appear in the Blocked Senders list. Clicking the pencil icon allows users to review and possibly edit the list of senders they have blocked. Users can also manually enter addresses rather than simply using the context menu from their message view.
