All services below except FTP serve domain-specific certificates in response to TLS SNI requests. If no domain-specific certificate matches the SNI request or if the client doesn’t send an SNI request, the service falls back to its default certificate, which you can manage below.
We recommend that you install the same certificate for each service.
iOS Mail Push Notifications trigger iOS devices to check for new messages when a message is delivered to an email account’s INBOX. To add support for this feature to your server, follow these instructions to obtain an APNs mail certificate, and then install it below.
iOS client devices must close and relaunch the Mail app to enable push notifications after the certificate is installed.
