Thanks for your patience while we worked to resolve this issue.
We have taken the unusual step of blocking mail to and from certain domains on our primary mail server that are not (to our knowledge) sources of spam. These domains are:
Please see the full details on the company blog.
The relay server is once again back online. We apologise for the inconvenience, and are working with the affected client to ensure that this problem is addressed.
The relay server is again offline while we clean up spam. It will be back online again within about half an hour.
The relay server is back online, and the source of the spam has been blocked until that client has re-secured their mail server. Thanks for your patience.
The relay server is offline for a few minutes while we clean up some spam that has been submitted through it. We’ll post an update here when it’s back online.
For the last couple of days we’ve been seeing email to zamtel.zm addresses queued on our mail servers. Not sure what’s happening on their end, but our systems are working fine and mail to other destinations is being delivered normally.
Also, the delivery issues with iwayafrica.com addresses that we’ve been seeing for several months now — in fact, the better part of a year — continue. Email sent to these addresses is usually not delivered for several days, if at all. Again, this issue is with the destination mail servers, and is not under our control.
The spam has been removed from the relay server’s mail queue and it has been restarted. We’re working to resolve this issue with the client in question, and will do our best to ensure that this situation does not happen again.
Although the client mail server that had been relaying spam had apparently been cleaned up, it has been compromised again and has been blocked from accessing the relay server. The relay server has been stopped again while we clean up the mess. We’ll post an update here when it’s back up, and the offending server will remain blocked until we have an assurance from the client that it is no longer compromised.
We apologise for the inconvenience that this is causing.
This spam outbreak has been fully investigated, and the client’s mail server that was affected is being tended to. At this point the relay server’s IP address is no longer in any blacklist that we are aware of. All mail from all other clients that is routed through the relay server is flowing normally.
If you have any questions or concerns about this incident, please contact NinerNet support. Thank-you.
