NC027: Server migration starting now

9 December 2017 20:11:17 +0000

The mail server migration will be starting within the next few minutes.

NC027: Migration of main mail server to new hardware

1 December 2017 08:13:12 +0000

Server NC027 (the primary mail server) will be migrated to new hardware during our regular weekly maintenance window next weekend. This maintenance will start at 20:00 UTC on Saturday 9 December 2017, and should conclude within one to two hours. During this time the mail server will be offline. This means that all incoming mail to domains hosted on this server will be queued on the sending servers, and delivered to this server when it comes back online. It also means that you will not be able to send email during this period.

We will post an update here shortly before, at the start of and following the maintenance.

If you have any questions or concerns, please contact support to let us know. Thank-you.

NC023: Server migration complete

19 November 2017 01:32:47 +0000

The migration of the relay server to new hardware has been completed. The server was offline between 20:20 and 20:39 UTC. Additionally, it now has more disk space and is accessible over IPv6 as well.

The relay server migration will be starting within the next few minutes.

NC023: Migration of relay server to new hardware

17 November 2017 07:22:19 +0000

Server NC023 (the relay server) will be migrated to new hardware during our regular weekly maintenance window this weekend. This maintenance will start at 20:00 UTC on Saturday 18 November 2017, and should conclude within an hour. During this time the relay server will be offline.

This maintenance only affects clients using the relay mail server; it does not affect operation of the regular email server that processes the vast majority of the mail carried by NinerNet.

We will post an update here shortly before, at the start of and following the maintenance.

If you have any questions or concerns, please contact support to let us know. Thank-you.

NC027: Spam cleaned up

7 September 2017 13:23:50 +0000

We have cleaned up the spam on server NC027 and managed to funnel most of the delayed email through our relay server. Although the primary mail server’s IP address is not in a couple of the major blacklists, we are still in some niche ones with major ISPs and mail providers. We have been working to have the IP address de-listed where that is possible, but manual processes like these can take a couple of days.

In the meantime, at the moment most email is flowing normally, but email to most domains will still be delayed for the next few hours.

NC027: Mail server issues

7 September 2017 11:39:46 +0000

We have cleaned up server NC027 after a client’s email account was compromised, resulting in thousands of spams being sent from the mail server. This is having a negative impact on email being sent from the server, as its IP address is now in anti-spam blacklists. This means that outgoing email sent from our clients will be bounced or delayed until the blacklist realise that the spam from our mail server has stopped.

We are working on implementing a workaround through one of our other, clean mail servers, but unfortunately it will be several hours before outgoing email to most domains is delivered normally.

These incidents usually arise after a computer has been infected with a virus. The virus then sends the email password back to the person or organisation controlling the virus, and they then use that information to compromise that email account on the mail server, using it to send thousands of spams from the account. Please ensure that you install, use and update an anti-virus program on your computer to ensure that this doesn’t happen to your email account.

We apologise for this incident. Please contact us if you have any questions. Thank-you.

NC027: Previous issue with outbound email to MessageLabs

8 April 2017 07:56:47 +0000

Further to our last post of two days ago, a little research digs up the fact that Symantec/MessageLabs “had a major incident … that led to an issue with multiple customers.” As we suspected, the problem was not with our mail server.

The message backlog was actually finally cleared within a couple of hours of that post.

NC027: Issue with outgoing mail to MessageLabs/Symantec

6 April 2017 13:36:18 +0000

For several hours now we have been noticing that emails sent to domains hosted by Symantec on mail exchangers running their MessageLabs service (or the service formerly known as MessageLabs) have been stalled on our mail server (NC027) with errors such as the following:

(delivery temporarily suspended: lost connection with cluster6.us.messagelabs.com[216.82.242.46] while sending message body)

Particularly, messages with multiple recipients seem to be stalling like this, while other outbound emails to other domains not hosted by Symantec seem to be going out with no problem. Some messages appear to be going through over time, but not all.

Destination domains that seem to be affected by this include the following:

  • barrick.com (Barrick Gold Corporation)
  • sc.com (Standard Chartered)

We’re continuing to monitor this situation, but at this point there doesn’t seem to be anything that we have the power to do.

NC027: Mail server emergency maintenance

23 February 2017 16:22:59 +0000

The mail server (NC027) was shut down between 16:08 and 16:11 UTC this (Thursday) afternoon for some emergency maintenance. This would have resulted in a brief interruption in your ability to send and receive email.

If you have any questions about this, please contact us. Thank-you.
