On Nov 4, 2020 at approximately 12pm the Cogeco.ca mail server began blocking outbound email from the Ocean platform. Although we have not heard a formal explanation from Cogeco, it may be related to a spike in use of Ocean patient messaging which triggered a spam blocking rule.
As a result of the block, emails sent to @cogeco.ca addresses are not being delivered. We have opened a ticket with Cogeco support asking for the block to be lifted ASAP, but have paused email sends to that domain for the time being to avoid additional email loss.
We will continue to update this ticket with information as it becomes available.
Nov 5, 2020 11:00am: Email deliverability to @cogeco.ca addresses from Ocean appears to no longer be blocked and we have resumed sending email to Cogeco.ca recipients.
