Maintenance
US IMAP email server downtime

On 22 July 2026 at 10:00 am US/Central time (UTC -5) one of our US IMAP email servers will be shut down for infrastructure maintenance. The server will be offline during the maintenance and the expected downtime is 6 hours.

Affected customers will be notified individually via email.

No incoming mail will be lost while the server is offline. Mail that arrives during the maintenance will be deferred and delivered once the mail server is back online.

We realize that the timing of this relocation is not ideal. If you have business-critical mailboxes and would like them to be available during the maintenance then please email support@opalstack.com or reply to this message to make arrangements to have your mailboxes migrated to a different IMAP server prior to the scheduled maintenance date.

If you have any questions or concerns regarding this maintenance then please email the Opalstack support team for assistance.

Temporary mail certificate error, now resolved

At approximately 0500 UTC today (19 April 2024) there was a problem with a routine certificate update which caused invalid certificates to be deployed to our mail servers.

The change was rolled back after about 90 minutes and the mail services are operating normally at this time.

Mail forwarding issue (now resolved)

At around 16:15 UTC on 16 April 2024 a configuration update was deployed to our forwarding mail servers. The update inadvertently included some old configuration that we used when we initially rolled out SRS mail forwarding a few months ago. As a result of this error some mail sent to customer forwarding addresses may have been bounced back to the sender.

The configuration has been corrected today 17 April 2024 as of 19:05 UTC and the old configuration has been purged from our management systems to prevent this from occurring again.
