Urgent maintenance on October 21, 2026

Dear mailbox customers,

Due to urgent maintenance work, there may be temporary disruptions to various services today.

As you may have heard in the news, two critical zero-day vulnerabilities in PHP (CVE-2026-109618 and CVE-2026-109619, also referred to as "PHP2Shell") were disclosed on October 21, 2026. These vulnerabilities allow unauthenticated remote code execution on affected web servers.

To protect our systems and your data, we have taken some of our services offline as a precautionary measure. As soon as the official security patches released by the PHP Foundation are available, we will apply them and re-enable full service access right afterwards.

Thank you for your understanding and patience as we prioritize the security of your data.

Your mailbox team
