IMAP improvements

We are currently tweaking the IMAP configuration on our servers to allow more concurrent logins, which should improve responsiveness for email clients such as Thunderbird, Apple Mail, Outlook, and smart phones.

We appreciate feedback on how we are doing!

Runbox listed by backscatterer.org

Some users may have had mails bounce recently  with an error referring to a blacklist called ips.backscatterer.org, or no clear error at all. This is caused by the sole blacklist runbox’ mailserver IP address is on, which is a list which only blacklists mail servers for handling mail bounces in certain ways. Many other mail servers does it in the same way we do, but our large volume and problems with the IMAP bandwidth quota (now solved) have probably caused us to be on this list on and off for years.

This is NOT a spammer blacklist in other words, and it is irresponsible and uninformed to bounce mails based on any single IP blacklist, but especially this one. And recently, it seems that far more services use this list in such a manner. If your mails have bounced from a domain where you have contacts, we recommend sending them the following link:

http://www.backscatterer.org/?target=usage

We may become delisted as of Oct 12, and will update this post then if so.

UPDATE: We are currently delisted, but will update this post if we are re-listed.

Regarding usage of Google Analytics

Recently the Norwegian Data Protection Authority concluded that usage of Google Analytics might be illegal in Norway.

As Runbox is based in and operates from Norway, a number of our users has expressed concerns regarding whether Runbox does use Google Analytics and how.

Runbox users do not need to worry. We have stopped using any type of Analytics and you can read about it here.

Runbox does indeed use Google Analytics on public pages, such as www.runbox.com to gain statistical information about where visitors come from, how much time they spend reading various public pages, e.g. about our pricing plans etc. However, Runbox does not use Google Analytics on logged-in pages.

Norway gives strong protection to personal data and Runbox has a strict privacy policy. Runbox does not allow third parties to access your information. Therefore, once a user reached the pages which require authentication, neither Google Analytics nor any other third party service is allowed to monitor their activity, as theoretically such third party could obtain information about user’s private information, such as their contacts and email contents. At Runbox we guard users’ privacy and such leak of information would be non-acceptable.

[Solved] Services temporarily inaccessible 16.08.2012

We are having problems with a central database server and all services are inaccessible while we work to resolve the problem.

We apologize for the inconvenience and will update as soon as we know more.

Follow us on Twitter for instant updates: https://twitter.com/Runbox

Update 23:02 CET:

The main database server is overloaded and we are working on several theories including hardware failures and NFS (network file system) problems.

We are working to regain some access via web meanwhile.

Update 23:09 CET:

We are restarting the main database server now and expect to be online in a few minutes.

Update 23:33 CET:

We have started web services and will soon follow with POP and IMAP and finally email delivery.
Email sent to Runbox during the downtime has been queued on our MX servers and will be delivered shortly.
We will continue investigating what caused the problem and already have new database servers on the way.

Update: 00:10 CET:

 All systems are working as they should. We will continue to look into this to make sure it does not happen again.

www.runbox.com under attack

We are currently experiencing a distributed attack from a large number of IP addresses, which is intermittently denying service to our customers and users.

We appreciate your patience while we work to resolve this, and ask that you use https://beta.runbox.com meanwhile.

UPDATE: We have put in place counter-measures that seem to take care of this problem.

Spam filter improvements

We’re currently tweaking the Runbox spam filter configuration to catch more spam.

Specifically, we’ve fixed an error that caused messages with a valid DKIM (DomainKeys Identified Mail) header to pass straight through the spam filter. Since some spam unfortunately includes such a header we now scan messages regardless of their DKIM status.

We have also tweaked the spam score given to messages sent from dynamic IP addresses, which can also be an indication of spam (although most such messages are of course innocent).

We would be interested in your feedback regarding the spam situation in your own account and whether you see any improvements.

Thank you!
