We are currently experiencing IMAP and POP access issues and are investigating what is causing these.
We apologize for any inconvenience caused.
UPDATE 18:45 CEST: We are restarting IMAP related services and expect access to be restored shortly.
UPDATE 20:00 CEST: We are still investigating the issue which appears to be caused by excessive traffic.
UPDATE 20:45 CEST: There appears to be an ongoing attack against our services and we are working to mitigate this. We appreciate your patience and suggest you use our web service at https://runbox.com/app in the meantime.
UPDATE 21:40 CEST: Our system administrators are continuing investigations and we apologize for the inconvenience caused while we utilize all available resources to resolve this problem.
UPDATE 23:35 CEST: The situation is currently much better and services appear to be working normally. Although the symptoms looked like they could be caused by an attack on our services it is not entirely clear if this was the case and we will gather more evidence and investigate further. We are monitoring the situation and there will be more done on this issue in the coming days. Apologies again for the inconvenience.
