Mailprotector

If you are using Mailprotector, you may need to allowlist our domains, IPs, and URLs within their system. 

Here are some resources they provide.

According to Mailprotector, allowlist would only be implemented for the CloudFilter product (SEG Filter) and not the Shield product(SEG+API Filter), since that is a zero-trust solution.

If you have any questions regarding Mailprotector, please reach out to their support team.
