Senders are set to get a bounce message explaining why the email was blocked for inbound mail. Google is advising people who want to send non-malicious .js files to utilize storage solutions like Google Drive or Google Cloud Storage to do so.
Gmail already has a number of safeguards in place to protect the safety of users. A visual indicator tool showcases a question mark sign if an individual receives a message from someone who can’t be authenticated by either Sender Policy Framework (SPF) or DKIM. It’s meant to act as protection against spam.
Another tool focuses on warning Gmail patrons about unsafe links in an email. URLs to known malware or phishing sites instantly prompt up an alert warning them away from the page.
