When a service receives a TLS SNI request, the service tries to
serve a certificate that matches that SNI request. If no such certificate
exists or if the client doesn’t send an SNI request, the service serves 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.
