What Are Quarantine Emails?
Quarantine emails are messages that are flagged by an email security system and held in a quarantine folder instead of being delivered to the recipient’s inbox. This is done to prevent potential security threats such as spam, phishing, or malware.
Why Are Emails Quarantined?
Emails may be quarantined due to the following reasons:
- Detected as spam or junk mail
- Identified as phishing attempts
- Containing suspicious attachments or links
- Failing authentication checks (e.g., SPF, DKIM, DMARC)
- Blacklisted sender domains or IP addresses
How to Manage Quarantine Emails?
- Check the Quarantine Folder Regularly – Ensure you review your email quarantine folder frequently to avoid missing important messages.
- Release Safe Emails – If an email is mistakenly quarantined, use the email security system’s options to release it to your inbox.
- Mark Senders as Safe – Add trusted senders to your safe list or whitelist to prevent future quarantining.
- Report Suspicious Emails – If an email appears harmful, report it to your IT team or email provider instead of opening it.
- Adjust Email Security Settings – Organizations can fine-tune security policies to reduce false positives while maintaining protection.
