Spam Filtering and Custom Email Filters

SiteForge Email includes two separate features:

This guide explains how to create custom filters in webmail and includes a quick reference for spam filtering settings.

What email filters are​

Custom mail filters let you automatically process new incoming emails. For example, you can:

  • Move emails from a specific sender to a selected folder
  • Move emails that contain a word in the subject to a folder
  • Send a copy of selected emails to another address
  • Organize messages from customers, orders, invoices, and notifications

A filter set is a container for one or more filters. You may see names such as filters or another custom name. This is normal. Inside that filter set, you create individual rules such as Move Gmail messages to Customers.

Where to access webmail​

You can access webmail in two ways:

  1. Global webmail: https://webmail.siteforge.ie
  2. Domain webmail: https://mail.customerdomain.com

Replace customerdomain.com with your own domain, for example: https://mail.example.ie.

How to create a new folder​

  1. Log in to webmail.
  2. Go to Settings.
  3. Open Folders.
  4. Create a new folder, for example: Customers, Orders, Invoices or Offers.
  5. Save the folder.

How to create a filter​

  1. Log in to webmail.
  2. Go to Settings.
  3. Open Filters.
  4. If there is no filter set yet, create one. A simple name such as filters is recommended.
  5. Make sure the filter set is active.
  6. Click Create to add a new filter.
  7. Enter a filter name.
  8. Make sure the filter is enabled.
  9. Choose the condition, for example:
  10. Choose the action, for example:
  1. Click Save.
  2. Send a new test email to confirm the filter works.

Example 1: Move emails from a sender to a folder​

Example rule:

  • Filter name: Customer - Sender Rule
  • Condition: From contains [email protected]
  • Action: Move message to Customers

Example 2: Move emails by subject​

Example rule:

  • Filter name: Invoices by Subject
  • Condition: Subject contains invoice
  • Action: Move message to Invoices

Example 3: Send a copy of selected emails to another address​

Example rule:

  • Filter name: Copy Orders
  • Condition: Subject contains order
  • Action: Send copy to [email protected]

Important notes​

Custom filters are created in webmail, not in the hosting panel.

important

Filters only work for new incoming messages after the filter is saved and active. Existing messages already in the mailbox will not be moved automatically.

Troubleshooting​

  • If the filter does not work, check that the filter is enabled.
  • Check that the filter set is active.
  • Use contains instead of is equal to when filtering by sender, because the sender field may include a display name such as John Smith <[email protected]>.
  • Test with a new email after saving the filter.
  • If forwarding or copying to the same Gmail address used to send the test email, Gmail may hide the message in the same thread or treat it as a duplicate. Test with a different address.
  • If the filter moves messages to a folder, make sure the destination folder exists.
  • If the problem continues, contact SiteForge support.

Spam filtering settings in the hosting panel​

You can manage spam filtering in the Hosting Panel under Email Accounts → choose the mailbox → Spam Settings.

Spam folder threshold​

Incoming emails are scanned and assigned a spam score. Messages above your spam threshold are moved to the Spam folder.

  • Strict (for example 4): More aggressive filtering, with a higher chance of false positives.
  • Lenient (for example 8): Fewer false positives, but potentially more spam in the inbox.

Rejecting high-risk spam​

For very high spam scores, you can reject messages automatically so they are not delivered.

Greylisting​

When enabled, suspicious senders are temporarily deferred. Legitimate mail servers retry delivery, while many spam bots do not.

Allow and block lists​

You can always allow trusted senders (whitelist) and always block unwanted senders (blacklist).

Email authentication​

SiteForge automatically manages DKIM and SPF alignment for your domain to improve deliverability and reduce spoofing risk.
