2. In the Junk manager, there is a Block Senders rule. Select the rule, and then click the underlined text in the Rule description textbox, see screenshot:

3. In the popped-out Text Contains dialog box, you can add new senders, edit the original senders or delete the unwanted senders as you need. If you want to add new senders to block,please do as this: 

• Click New button to open the Search Text dialog box;
• Type the address that you want to block into the New Search Text box;
• Click Add button to add it to the Search list box;

5. It returns to the Junk dialog, where you can observe that the underlined senders have been updated based on your changes. Ensure the Block Senders rule is still ticked, then click OK to finalize the settings and close the dialog.

Tips:

1. Click the Enable Junk Email Filter again will turn off the whole Junk feature. If you only want to disable a certain rule, please go to the Junk dialog, and uncheck the rule.

2. A right-click menu is provided for quick selection of rules if there are multiple rules in the Junk dialog box.

• Select All: Select all rules in Junk manager.
• Unselect All: Deselect all rules in the Junk manager.
• Inverse: Reverse the status of the current selection. 
• Select up: Select the rules above the current selected rule(including the current rule).
• Select down: Select the rules below the current selected rule(including the current rule).

3. In the Junk dialog box, there are some example rules which can help you to understand how to create rules you need.

4. In the Junk dialog, if your rule conditions are too long, you can check Display the rule description inline wrap option to make the rule inline wrap.

5. If you have created multiple rules in the Junk dialog box, they will be executed in order from top to bottom. For instance, if an email meets the criteria of the first rule and is moved to the Junk folder, subsequent rules (like the second or third) won't be applied to that email. However, if an email matches the first rule to remain in the inbox but also fits the criteria of the second rule to be moved to the Junk folder, it will still not be relocated to the spam folder.
