DirectAdmin allows you to block emails containing the Stop word.

**1**. Log in to your DirectAdmin Account.

**2.** In the **E-Mail Manager** section, click on **SPAM Filters**. Alternatively, type **SPAM Filters** in the **search bar**, and the option will appear. Click on it.

**3.** Under **Block By**, select the **Stop Word** option from the **drop-down** menu.

**4.** In **Value**, type the stop word you want to block.

**5.** Click on **Block**.

You can add the Stop word as many times as you want. However, if you want to avoid blocking partial matches with other words, use space before and after your Stop word.
