Apple Mail Security: Disable Loading of Remote Content

See also all security topics.

Spammers like to send emails with tiny 1 X 1 pixel images; if the image is loaded, they know they have a “live one”. Don’t do this to yourself, it’s just inviting more spam. But it need not be hidden; any remote content in an email serves the same “live one” purpose.

Make sure the Load remote content in messages box is unchecked as shown below.

When reading a mail message, you can always Load Images in any particular email by clicking the Load Images button at the top right of the mail message.

Tip: another way to detect if a message is a scammer is to display extra message headers. These often reveal skanky details that are a big red flag.

Ensure that Load remote content in messages is off (unchecked)
