Customers firewalling their mail server to accept only DuoCircle's IP pool need to add the new EU IPs to the allowlist; the full IP list is published in DuoCircle's support knowledge base. To filter exclusively in the EU, point the MX record to mx1.eu.mailhop.org. To stay exclusively in the US, use mx1.us.mailhop.org.
