How to Block/Unblock A Sender In Thunderbird


Have you ever received an eMail from someone you do not want one from? I know I do, and many of my clients do, too. It can be very frustrating receiving messages from unwanted senders. The best way to deal with this is to block that sender’s eMail address. Many people use Mozilla Thunderbird as their primary eMail application. So I figured, ‘Why not show you the steps on how to block a sender’s eMail through Thunderbird?’. This will also delete the sender’s eMail immediately (almost like call blocker on your phone). This is a very helpful step-by-step guide that will keep the stress down when checking your mail.

How to Block a Sender’s eMail in Thunderbird

Step 1: Open your Thunderbird eMail application. Most of us will have it on the Task Bar. You are looking for this Logo– click on it

Step 2: Find one of the eMails that you received from the sender. Open the eMail and then right click on the sender’s eMail address at the top of the eMail.

Step 3: This will bring up a drop-down menu which you will want to select “Create Filter From…”

Step 4: The next window that will appear is “Filter Rules” and the address you selected will be auto-filled in the filter. If you want to add more eMail addresses, just click the Plus Sign (+) next to the first eMail. Make sure to name the filter “Block Sender” or something similar.

Step 5: Here you will want to head down to the bottom box (Perform these actions). Now you will want to Click the down-arrow next to “Move Message to” wording.

Step 6: This will bring up a drop-down menu. You will want to choose “Delete message.” Now click OK

Magic! If the sender tries to eMail you again, it will automatically go to the desired folder. If you selected Delete Message, it will go there rather than your Thunderbird Inbox. You can reverse this if you forgive that sender at a later time. Unblocking is very easy to do compared to setting up the Block.

Bonus:

Removing a sender from the block list (unblocking)

Step 1: At the top of your Thunderbird eMail application choose “Tools” From the drop-down menu, select  “Message Filters”

Step 2: In the the Message Filters box, click once on the Filter name. On this one you will click on “Block Sender,” (or whatever you titled your filter). Now click Edit

Step 3: The next step is to just Click the Negative Sign (-) next to the blocked eMail you wish to unblock. Click OK once you are done. Now this can only be done this way if you have more than one eMail set up to be blocked in the filter. If you only have one, then you have to delete the entire filter

The way to do this is when you are on the “Message Filter” window, select the filter you want to delete. Then, just click on the “Delete” button to the right

So there you have it! You can now block and unblock sender eMails.
