Understanding Mimecast Email Delivery Warnings
Mimecast is a leading provider of email security and management solutions, offering a range of services to protect organizations from email threats, such as spam, malware, and phishing attempts. While Mimecast is highly effective in safeguarding your email communication, you might encounter email delivery warnings under specific circumstances. Here are some common scenarios that trigger Mimecast email delivery warnings:
1. Large Email Attachments
When an email contains large attachments, Mimecast may apply additional scrutiny to ensure efficient delivery. Large attachments can slow down email delivery and may trigger temporary delivery delays.
2. Suspicious Email Content
If an email's content exhibits characteristics commonly found in spam or phishing attempts, Mimecast's advanced security algorithms might flag it as potentially malicious. While this is a vital feature to protect users, legitimate emails with certain keywords or attachments may inadvertently trigger a warning.
3. Email Reputation and Authentication
Mimecast heavily relies on sender reputation and email authentication methods like SPF, DKIM, and DMARC to verify the legitimacy of emails. If your domain or email server lacks proper authentication, Mimecast may issue a warning to safeguard its recipients.
Troubleshooting Mimecast Email Delivery Warnings
Receiving a Mimecast email delivery warning doesn't necessarily indicate a problem with your email delivery. However, it's essential to address these warnings promptly to ensure smooth email communication. Here are some troubleshooting steps:
1. Check Email Content
Review the content of your email for any suspicious elements or spam-like characteristics. Avoid using spammy keywords, excessive exclamation marks, or misleading subject lines.
2. Optimize Attachments
If your email contains large attachments, consider using file-sharing services or cloud storage links to reduce the attachment size and improve deliverability.
3. Authenticate Your Emails
Properly authenticate your email domain with SPF, DKIM, and DMARC records to establish a trustworthy sender reputation.
4. Review Mimecast Policies
Understand Mimecast's email security policies and adjust your email content and attachments accordingly to comply with their guidelines.
