Server upgrade underway [Completed]

As previously announced we’re now taking down one of the application servers in order to upgrade it.

Most likely only some users will be affected while others can keep using the email service normally while the upgrade takes place.

We will keep you updated here as the work progresses.

UPDATE 08:22 CET: We have installed the Flash Cache and are rebooting the server.

UPDATE 08:32 CET: We’re reconfiguring the server to work with the new Flash Cache.

UPDATE 09:00 CET: We’ve encountered some complications and will try a couple more things before reverting.

UPDATE 09:41 CET: We have problems with the upgraded kernel/network card combo and are trying to solve this now. We apologize for going outside the scheduled downtime window.

UPDATE 10:24 CET: We’re now installing a new network card to resolve incompatibilities.

UPDATE 11:01 CET: We’re still working hard to resolve remaining conflicts. Meanwhile, you can use the new Runbox 6 Webmail at, but note that some users won’t be able to open messages until we finish the upgrade.

UPDATE 11:17 CET: We are back up and fully operational again. Our apologies for any inconvenience caused by the prolonged downtime. 

UPDATE 13:50 CET: It seems we forgot to remove the redirect on This is fixed now!

  1. How are you not connected? Via Webmail, IMAP or POP?

    IF you are using a email client, did you try to restart it?

  2. According to this site the “upgrade” has been completed but now I can’t access any of my mailboxes. It was bad before for those of us who use Apple-based e-mail but at least I could click the “get mail” button 30 times (yes, I counted) and still get most of my messages. When should I expect to get access again?

  3. We do have problems with Apple Mail now. The developers are working hard at it. It seems Apple Mail now wants APOP to login and we find that very strange. It has nothing to do with the server upgrade.

  4. After the upgrade I cannot get mail anymore on my windows 8 phone. An error message pops up and says the certificate for the imap server is incorrect. Email on my phone worked before the upgrade, but I can’t seem to get it to work now. Is there anything I can do to fix this? Any help would be greatly appreciated.

    Thank you,


    1. We recently updated the SSL certificate for IMAP, POP, and SMTP. Could you try restarting your email program or your phone and see if that helps? If not, please set the server address to if it isn’t that already. Thanks!

  5. I have had the same problem as Chris with getting my emails on my iPhone5 since the upgrade. I just get ‘The mail server “” is not responding. Verify that you have entered the correct account info in mail settings’
    I have tried the advice given above but to no effect – and it all worked perferctly before the upgrade. Any suggestions or help please?
    Thank you

    1. Peter,

      Thank you for the feedback — it’s possible that the new SSL certificate we installed on the servers requires some email clients to remove and set up their account again, although it shouldn’t be necessary…

  6. Many different accounts (all POP) are working on Thunderbird, failing on Apple Mail. Very little other information can be squeezed out of Apple Mail, but I’ve tried both APOP and Password, neither of which works. It has now been a couple of days since I pulled down any new mail.

    I really can’t delete the account and reset it — this account has existed forever, and synching it all up again would take forever. Any other thoughts?
