Push notifications do not work with IBM email servers

Sophos Secure Email does not receive push notifications for newly arrived emails if a IBM Domino or Traveler email server is used.

Email encryption and verification of email signatures not supported

Sophos Secure Email does not support email encryption as done so with for example S/Mime or PGP. Sophos Secure Email furthermore does not support the verification of digitally signed emails. However, emails that are only digitally signed using S/Mime can be displayed, but the signature cannot be verified. Using other technology for signing emails (e.g. PGP) might result in the email not being displayed at all.

iOS 13 implements a new voice control system. Due to these changes in iOS 13, the dictation feature is currently no more working within Sophos Secure Email.
