To ensure delivery from FreeLists to email accounts you host or for inbound SMTP policies you have control over, you may want to add the outbound IPs in this list to your global allowlist(s). All mail from FreeLists will come from one of these IP addresses (and this is reflected in our SPF record.)

This list, though relatively static, is subject to change at any time!

• 23.23.80.81
• 34.228.148.125

Allow/safe-list configurations are an anti-pattern but certain anti-spam services and devices have a reputation for questionable policies where a blanket trust of FreeLists is the easiest way to ensure reliable delivery.
