Applies to

  • ONTAP 9.14 or earlier
  • All SnapCenter versions
  • AutoSupport (ASUP)
  • SMTP authentication using Transport Layer Security (TLS)

Issue

Prior to 9.15.1, ONTAP AutoSupport over STARTTLS is not supported. However, 'cloud' SMTP service providers, such as Microsoft Office 365 and Google Gmail/G-Suite, typically require STARTTLS for external email destinations and recommend it for internal email destinations as well.

Note: EMS email transmission is sent from ONTAP via event filter function, which is also not supported.
