Pulsant engineers have been alerted to mail flow issues affecting the onyx mail platform.
This system has been listed on several blacklists, which is causing issues with mail flow.
There have been various changes to the current server configuration, which has mitigated some of the issues and allowed for de-listing from blacklists.
However, due to the legacy configuration of the mail server, a replacement mail server has been commissioned.
Given the current impact on mail flow, an emergency change has been scheduled and approved to restore full system stability.
During this time there will be disruption to mail flow, as current mail queues are flushed and the new server is brought online.
The maintenance will take place during the following window:
Start: 12/01/2021 @ 20:00 GST
End: 13/01/2021 @ 01:30 GST
During this maintenance the mail services will be unavailable for short periods of time.
If you have any questions, please raise a ticket or contact your service manager.
For your reference, please see our status page for updates on planned maintenance and service incidents. This can be found at http://status.pulsant.com
Please accept our sincere apologies for any inconvenience this may cause.
