On or soon after February 13, 2017 iSpartan Gmail users will no longer be able to send or receive email with Javascript files (.js) attached.

Users who need to share Javascript (.js) files should use Google Drive or other Cloud storage solutions.

For security purposes, Google prevents attaching certain file types, such as .exe and .bat, to email.  Google will now treat Javascript files (.js) similarly.

Users who try to attach a file of a restricted file type receive notification from Google explaining why the attachment is not permitted.

Non-Gmail users who send an email with a Javascript attachment to an iSpartan account will receive a bounce noticed, explaining why the message was not delivered.

Tip: Javascript files are permitted in Google Drive. Use Google Drive to share these files with collaborators.
