Permanently block domain in Gmail

My inbox is being destroyed right now—I’m getting 3–4 messages a minute from a specific host ( for some reason. I would really like to just prevent any and all email from his host from even getting to my inbox.

I have created a filter in Gmail, the problem is that Thunderbird, which is setup via IMAP, is placing those messages in the trash. My trash is growing by 5 messages per minute.

It’s taking its toll on Thunderbird, and my CPU usage.

Can’t I just somehow prevent some known bad host, or domain, from getting into my inbox?

I don’t want to “put these files in the trash”—that’s just another folder in Gmail terms.

I want them to either A) be deleted not placed in a trash folder, or B) ideally never even get that far.

Is this possible?


You can do that using a Filter.

Steps to follow:

  1. Go to setting page of GMail.
  2. Click on the Filters Tab.
  3. Click on “Create a new filter” buton.
  4. In the “From” field write “*” (without ” ” – if your mails are comming from addresses like,, etc…)
  5. Click on the “Next Step” button.
  6. Check the “Delete it” and “Also apply filter to ** conversations below” (here “**” is the email count) checkboxs and click “Create Filter”

All mails from that type of email address will be deleted (including messages in the Inbox) automatically.
