    We’re aware that the SSL certificate for the Pro Email subdomain has expired, which may cause certificate warnings or connection issues in some email clients. Our developers are actively working on resolving the issue as quickly as possible. We’ll provide another update as soon as the certificate has been renewed and services are fully confirmed.

    We've now resolved the incident. Thanks for your patience.
