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: Outgoing mail may be delayed

31 July 2017 04:29:48 +0000

An email account on server NC027 was compromised in the last few hours, and it was used to send spam. This problem has been addressed by suspending the account, but the result is that outgoing email from the server may be delayed for the next few hours until automated anti-spam systems around the Internet react to our cleaning up the problem.

We apologise for this problem, and remind everyone to ensure that their computers are scanned regularly for viruses.

If you have any questions about this, please contact support. 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.

NC027: Mail server report

30 January 2017 13:18:24 +0000

We have not yet been able to determine a cause of the problem with the mail server (NC027). It seems that it stopped processing mail at 08:46 UTC, which means it was unavailable for 56 minutes until it was up and running again at 09:42 UTC. The server didn’t become completely unresponsive to monitoring until about 09:25 UTC, which is when the problem came to out attention. A few minutes later, after determining that the server was completely inaccessible and posting to our status page, we issued a full reboot. After a few minutes of disk scanning, the server was back online and processing email.

We apologise again for this brief interruption in service. If you have any questions, please contact us and we will be happy to respond.

NC027: Mail server rebooted

30 January 2017 10:01:07 +0000

The mail server (NC027) was rebooted and back online at 09:42 UTC. We are looking into the problem and will post an update here within the next two hours.

We apologise for the inconvenience.

NC027: Problem on mail server

30 January 2017 09:34:18 +0000

We are aware of a problem with the mail server (server NC027). We are looking into it and will post an update here as soon as possible.

NC027: Mail server back online

23 November 2016 07:28:27 +0000

The mail server (NC027) has been restarted after cleaning up after a spammer. It was down for eight minutes between 07:09 and 07:17 UTC.

As a result of this incident, our mail server is being blocked by some mail services. We will work to have those blocks removed before they expire, but this will take some time.

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