How do I configure my Anti-spam settings?

Overview

Spam filtering is enabled by default for all DreamHost hosted email addresses in order to provide you with the best email experience possible.

This article is a basic breakdown of how to use spam filtering on your domain. If you would like to read more detailed information on spam filtering, please refer to the following article:

Allow or Block addresses in the panel

Blocklist entries are email addresses or domains you never want to receive email from. Emails from blocklisted senders are quarantined regardless of the email's spam score.

An email that is sent to you from a blocklisted address won't arrive at your inbox. The sender receives a bounce message and the message does not deliver.

Allow list entries are email addresses or domains you always want to receive email from. Emails from Allow list senders are delivered to the inbox regardless of the email's spam score.

  1. To Allow or Block an address, navigate to the Anti-Spam page.
    edit button
  2. To the right of your domain, click the Edit Filter button.
  3. On the domain's email page, you have two options to create an Allow or Block.

Option 1 — Adding an Allow/Block list to all emails on a domain

  1. To Allow or Block an address, navigate to the Anti-Spam page.

    If you have enabled G Suite on your domain, your mail is hosted at Google where you must configure your filters. You will see this on the Anti-Spam page to the right of your domain.

  3. Click the Edit settings for example.com button at the top of the page.
    creating an allow or block list entry
  4. In the Emails from the address field, enter the domain like this:
    @domain.com
    This sets the SPAM domain as Allowed or Blocked for all emails under your domain.
  5. Click the Add Address button to save.

Option 2 — Adding an Allow/Block list to a single email address

  1. To Allow or Block an address for a specific email address (and not all emails on the domain), navigate to the Anti-Spam page.

    If you have enabled G Suite on your domain, your mail is hosted at Google where you must configure your filters. You will see this on the Anti-Spam page to the right of your domain.

  2. To the right of your domain, click the Edit Filter button.
    adding allow or block list to single address
  3. Click the Edit button to the right of an email address.
    adding allow or block list to single address
  4. On the specific email address page, and an address or domain to allow or block.
  5. Click the Add Address button to save.

Explanation of Allow/Block list options

Emails from the address

  • When entering an email, it can be individual email addresses user@EXAMPLE.com or one entry to cover an entire domain @EXAMPLE.com.
  • The limit is 100 combined Allow and Block list entries.
  • All addresses must be entered manually. There is no bulk-import of addresses.
  • If mail is correctly routing through MailChannels but is not being processed per the Allow/Block list, check the message headers. It's possible to use an email client to modify the headers to display one sender address when the message was actually sent from another address. You would then need to adjust your Allow/Block lists according to details found in the header.

Action

This is Always Allow or Always Block.

Enabling spam filtering on an existing domain

If you were previously using a domain at DreamHost but did not have spam filtering enabled, DreamHost strongly recommends enabling it.

To enable spam filtering on an existing domain:

  1. Navigate to the Anti-Spam page.
    enabling filter
  2. Click the Enable Filter next to your domain (only shows for domains with active email hosting).

Disabling Spam filters

Setting up alternative filters

If you do not wish to use the anti-spam filtering feature that DreamHost offers through the panel, you have a few alternatives for filtering incoming mail before it's delivered to your hosted user with DreamHost.

Below is a description of alternative junk-message filters:

Message filters
These are available through your account panel at Message Filters. This feature allows you to customize and create your own set of filter rules for each user. You can refer to the following article for details with this feature:

You cannot set up these custom message filters on a domain-wide basis. They must be created for each user you want them applied to.

Third-party filtering providers

You can set up third-party mail filtering services for your domain as well and have those filtering services deliver the mail to DreamHost mail servers once the filtering is complete. This can be setup through your account panel at Custom MX.

You can read more about how to set this up in the following article:
