Due to the effects of a a number of large spam botnets, customers will have experienced delays in mail delivery. The delays are due primarily to the farm of mail filter servers, which are in place to weed-out the spam, virii and malware attached to emails, becoming heavily loaded dealing with the mails received by these botnets. Specifically these botnets appear (at first analysis) to be related to a large number of trojans infecting mobile devices around the world.
Our teams have been working to, initially, add additional mail filter servers and incoming spools to keep with the increased load caused by these botnets. Over the coming hours and days we will be working to implement more robust solutions to combat this kind of anomalous traffic.
We apologise for the inconvenience that these delays may have caused.
We are currently experiencing an anomaly with the GandiMail service affecting mail reception. Our technical team is investigating the issue. Incoming mail is currently being deferred while the affected subsystem is being diagnosed. Outgoing mail is not affected by this incident.
We sincerely apologise for any inconvenience.
Update 11:00 CET: Mail reception has resumed, and incoming mails are being delivered, though with a bit of delay whilst the backlog is cleared.
Update: 15:30 CET: The incoming mail systems have now been returned to normal operation. The interruption was due to a dysfunction of the anti-spam/policy subsystem which created a backlog of mail queues on the inbound spools. The backlog has now been cleared.
