To maintain uninterrupted delivery of emails from Catchpoint, please follow the steps outlined below. These actions will help ensure that messages are not blocked or misclassified by your organisation’s email security systems.
1. Whitelist Catchpoint Mail Server IPs
To prevent legitimate alerts from being blocked, whitelist our mail server IPs in Microsoft Defender:
Steps to Whitelist IPs in Microsoft Defender Portal
-
Sign in to https://security.microsoft.com (Microsoft Defender portal).
-
Navigate to:
Email & Collaboration → Policies & Rules → Threat policies → Anti-spam -
Select Connection filter policy and click Edit connection filter policy.
-
Under “Always allow messages from the following IP addresses or address range,” add the following IPs:
64.147.163.75 => mx01.catchpoint.com 64.147.163.76 => mx02.catchpoint.com 64.147.163.77 => mx03.catchpoint.com 64.147.163.78 => mx04.catchpoint.com
- Click Save, then Close.
2. Monitor Your Spam/Junk Folder
If you suspect alerts are missing, check your spam or junk folders. Mark any Catchpoint messages as “Not Spam” to help train your filters.
3. Add Catchpoint to Safe Senders List
Add our domain (@catchpoint.com) to your email client’s safe sender list to ensure messages are delivered to your inbox.
4. Confirm Alert Routing
Review your alert routing rules to confirm that messages are correctly directed to the intended recipients.
5. Contact Support if Issues Persist
If you continue to experience issues with alert delivery, please contact our support team. Provide the affected email addresses and timestamps of missed alerts to help us investigate.
