Server NC036 is back online. It was down for 6 minutes between 02:31 and 02:37 UTC. We’ll be posting additional information about this shortly.
Server NC036 is back online. It was down for 6 minutes between 02:31 and 02:37 UTC. We’ll be posting additional information about this shortly.
Server NC036 (our primary mail server) will be undergoing emergency maintenance within the next few minutes. The server will be down for approximately half an hour.
We will post an update when we are done.
Shaw Communications Inc. and their mail filtering sub-contractor (Cloudfilter/Cloudmark) are again delaying, and now even bouncing, email sent to shaw.ca addresses. However, we have no way of communicating with Shaw mail server admins, so we cannot talk to them about how their filtering practices are non-standard and unpredictable.
Our mail server is still/again not in any of the 250 major blacklists that we monitor, so it is unclear why Shaw/Cloudfilter are causing this problem. If you are a Shaw customer, we strongly recommend that you contact Shaw and complain. We also recommend that you do not forward your email to any addresses on their domain.
Update, 2021-07-13 15:45 (PDT): Bounce messages will contain this line, or something very similar to it:
host shw-central.mx.a.cloudfilter.net[3.96.81.40] refused to talk to me: 421 shw-ibgw-4001a.ext.cloudfilter.net cmsmtp too many sessions from 178.62.195.26 AUP#CNCT
Normally bounce messages can be easily deciphered, but even we don’t know what this means or how it makes any sense.
Server NC036 has been rebooted and is back online. All functions have been checked, and all services are running normally.
If you have any questions, please contact NinerNet support. Thank-you.
Server NC036 will be rebooted shortly, following recent maintenance. It will be inaccessible for about one minute. We will post again when it is back online.
As of Sunday 6 June 2021 (Pacific Time), emails to shaw.ca are being delayed. This problem may also be affecting other domains owned by Shaw Communications Inc., but at this point we’re only aware of the issue affecting email to shaw.ca
The problem appears to be that Shaw has changed their MX record to point to a new, external mail filtering company. (The change is new; the mail filtering company is not new.) All emails to shaw.ca are being temporarily deferred, rather than hard-bounced. It’s unclear why this is, as our mail server’s IP address is not in any major blacklists of the approximately 250 that we regularly monitor. There is also no notice on Shaw’s “Service Updates & Outages” page, and no notification was received by Shaw customers of a planned outage.
We will continue to monitor this situation and, if we can, take any action to work around Shaw’s action and the unavailability of their mail system at the moment. If you have any questions in the meantime, please contact NinerNet support. If you yourself are a Shaw customer, we strongly recommend you contact them and voice your displeasure at your email being delayed and/or blocked.
Update, 2021-06-07 15:00 (PDT): We submitted two support requests to the company to which Shaw outsources their email, but they have been no help, suggesting that we have to contact Shaw directly. However, since they’re blocking our email and they don’t seem to have any kind of a corporate website, that’s rather difficult.
After our last reply to a ticket at 14:23 we checked the mail server to confirm that the copies to Shaw were blocked, and we found that almost all of the queued emails to shaw.ca addresses had been cleared; a few moments later all had been cleared and delivered.
So it seems that this issue has been resolved. However, we have had no contact from Shaw, so without an explanation for why their email stopped working we can’t be sure this won’t happen again.
The scheduled maintenance on server NC036 is complete. The ability to send and receive email was not available between 22:47 and 22:53 on 30 May UTC. The new disk space has been tested and all is running normally.
Thank-you for your patience. If you have any questions or concerns, please contact NinerNet support. Thank-you.
During this weekend’s maintenance window we will be adding hard drive storage to server NC036 to continue to provide more storage space for a growing number of growing email accounts. This maintenance is scheduled to start in a few minutes, it will conclude in less than half an hour.
During the maintenance the ability to send and receive email will not be available, both via standalone email programs (e.g., Outlook, Thunderbird, etc.) and the webmail. Incoming email will be queued on the sending servers until our server is back online again, after which it will then be delivered to our server and your email account. This may result in a delay longer than the planned length of the maintenance though.
Please monitor this status page to be notified of the end of the maintenance. If you have any questions or concerns, please contact NinerNet support.
Thank-you for your patience as we continue to work to improve our services to you.
Since about 05:00 UTC on 11 March we have noticed that emails to Microsoft’s free email domains — hotmail.com, outlook.com, msn.com, live.com and various other domains in various other TLDs — have been and are being significantly delayed, sometimes by twelve hours or more. This is not a problem with our mail servers; it is Microsoft that are deferring and refusing deliveries. If you look at their “service health” page, they claim that “Everything is up and running”, but this is not accurate — or true.
We are monitoring the situation, but there is little to nothing that we can do. We ask you to have patience when communicating with people who use this free email service, and if Microsoft cared to communicate with the public, we’re sure they’d ask that too.
The *.niner.net SSL certificate was renewed today and updated on all servers.
If you get any certificate errors in either your web browser or email program, please close down all programs, restart your computer, and try again. This should clear the cache of the programs in question and force them to download the new certificate information.
If you have any problems, please contact support. Thank-you.
