That means that GMail users can’t send or receive emails with .js file attachments. Anyone sending a .js file to a GMail user will find their email bouncing back to them with an explanation of why it wasn’t delivered.
If you try to send an email with a .js attachment, Gmail will give you an error message letting you know that your file type isn’t allowed and was “blocked for security reasons”. As an alternative, Google will suggest using outside storage, like Google Drive or Dropbox, and linking to the file from within the email. (There’s no getting around this by zipping up your file either, as Google will take a look inside the compressed file to check.)
It is strongly recommend enabling the view of file extensions (so often hidden by default!) so you can see exactly what kind of file type you’re dealing with, mitigating the risk of running a malicious file by accident, regardless of the operating system you run.Share This:
