At approximately 06:00 UTC on 17 May 2021 we inadvertently pushed the wrong set of SSL certificates to our US mail system.
Customers who attempted to access the mail system during that period may have seen certificate warning messages and would not have been able to access their mail.
The problem was fixed approximately 30 minutes later and the mail system has been working normally since that time. No incoming or outgoing mail was lost during the incident.
If you are still seeing a certificate error while attempting to use the US mail system then please restart your mail client and/or reboot your computer. If the problem persists then please contact Opalstack support for assistance.
