How to whitelist Aiwyn email sender IP ranges and bypass anti-spoofing

You can ensure that all Aiwyn emails are successfully delivered to your firm’s team and clients by updating your email security and filtering settings.

Whitelisting Aiwyn Sender IP Ranges

You can allow emails sent by Aiwyn to bypass filtering and blocking rules in your email service provider.

1. Open your email service provider’s administrative console, such as Microsoft 365.

2. Navigate to your email security or connection filtering settings.

3. Add the following sender IP ranges to your allowlist or whitelist:

   • 50.31.156.96/27 (50.31.156.96–127, transactional).

   • 104.245.209.192/26 (104.245.209.192–255, transactional).

   • 50.31.205.204/30 (50.31.205.204–207, transactional).

4. Save your changes and allow time for the settings to take effect.

For provider-specific instructions, refer to Microsoft’s documentation on whitelisting IP addresses in Microsoft 365.

Whitelisting The Aiwyn Domain

You can ensure emails sent from Aiwyn domains are accepted by your internal mail system.

Add aiwyn.ai to your allowed sender or domain whitelist so emails from Aiwyn can be received by your firm’s staff without interruption.

Bypassing Anti-Spoofing Policy In Mimecast

You can prevent Mimecast from blocking Aiwyn emails due to spoofing protection.

If your firm uses Mimecast and anti-spoofing is enabled, or if Aiwyn identifies delivery failures caused by a 550 SMTP error, create a new anti-spoofing policy that bypasses existing rules.

1. Open the Mimecast administration console.

2. Create a new anti-spoofing policy with higher priority than existing policies.

3. Configure the policy to allow spoofing for your firm’s domain when the source IP matches Aiwyn’s sender IP ranges.

4. Save and apply the policy.
