In July 2019 we are changing the SSL certificate we use on www.pobox.com to be the same wildcard certificate we use for our mail servers, *.pobox.com. Please see our page about the *.pobox.com certificate for its details.
The certificate used until that change is an Extended Validation certificate issued by DigiCert. The organisation displayed in your browser is FastMail Pty Ltd. Its details are below.
