How to Block Email Content

Automatic email content blocking is offered on most email clients.

HTML emails sent by other users may come with images and other embedded media. These images and other media are blocked to prevent viruses and other security breaches from occurring. The ability to block email content is activated by default on most email clients, but there are times when the feature must be reactivated to restore complete security to the program.

Instructions

1. Open the Microsoft Outlook email client. Click on "Tools" in the menu bar and select "Options."

2. Click on the "Security" tab in the Options window. Under "Download Pictures," click "Change Automatic Download Settings."

3. Check the box "Don't download pictures or other content automatically in HTML e-mail." Click "OK" when finished.

Blocking Email Content in Thunderbird

2. Click "Advanced" in the options tab. Under "Advanced Configuration," click the "Config Editor" button. Click "I'll be careful, I promise!" button when prompted with the warning.

3. Type "mailnews.message_display.disable_remote_image" in the "Filter" field of the "about:config" window.
