Email Security.Cloud Maintenance August 14, 2018 through September 30, 2018

47 days, 23 hours, and 45 minutes

The scheduled maintenance has been completed.


Scheduled maintenance is currently in progress. We will provide updates as necessary.


As previously communicated on November 29, 2017 via the Symantec Status Page; any TLS certificates issued/renewed across the Email infrastructure are now being issued by the DigiCert public certificate authority.

We would like to update our customers that we will be performing maintenance to complete the remaining set of our infrastructure with DigiCert certificates. This work will begin on August 14, 2018 and will be completed by September 30, 2018.

Impact In most cases, this change will not cause an issue, however, some customers/recipients may have configured their MTAs to trust only specific root certificate authorities. To which, these customer’s MTAs would fail to connect to Symantec’s Email, if their servers don’t trust the DigiCert public root certificate.
