How to blacklist senders?

faldringham · 18 Mar 2017, 04:37 AM

Is there a way to block specific "from" addresses, or to automatically redirect all emails from those addresses to a junk folder?

I am routinely receiving emails from certain senders that I do not want to receive emails from. I have flagged individual emails as spam, but I keep getting more from these senders.

When reading such a message, select More>Add Rule from Message...

You will then see a rule creation page which allows you to make a new filter. Be sure to click Save at the bottom right to cause the rule to be created.
Look at these key features of the rule creation page:
- Conditions
  - If all/any/none of the following conditions apply
  - The sender's email (click to change the condition)
  - is exactly (click to change the comparison type)
  - Remove (click to remove that clause)
  - Add Condition (click to add a condition clause)
- Action
  - Permanently delete the message
  - Send a copy to ...
  - Move the message to ...
  - Mark as read
  - Pin

Thanks for the tip!

Is it possible to do this without actually opening the email message--that is, to do it with only the message title and sender's name displayed?

For security reasons, I often don't want to open emails at all from senders I do not know.

Yes, you must open the message to allow creation of rules related to it's content. But as you will see this can be safe.

Fastmail goes through a lot of effort to open HTML messages safely. See this blog entry for the technical details:
Sanitising HTML

If you are worried about loading remote images from unknown senders (which you should be), go to Settings>Mail>Preferences>Load remote images and select either the 2nd or 3rd choice.

As long as you use that feature to not automatically load remote images, the message will be displayed securely (not allowing dangerous scripts to execute) and the sender won't know if you read their message (since you are not downloading any web beacons/bugs).
