Another iPhone ‘LIST-STATUS’ issue..

Posted on: February 13th, 2019 by

A little more than a year ago, we found and worked around an issue that caused iPhone users to have problems with IMAP connections to Kolab Now. The issue made it problematic for such users to list and read their IMAP folders.

Back then we worked around the issue by suppressing the LIST-STATUS option for IMAP connections, which made everything work for a while.

This week we again started getting a number of reports about similar symptoms from iPhone users, and we of course investigated those reports as fast and appropriate as we always do.

We quickly found, that a change was made in January to fix an issue for  Outlook users, and that one part of that change was – you guessed it – to undo the suppression of LIST-STATUS. Hence, IMAP connecting iPhone users were getting right back into almost the same situation that they were in a year ago.

Where as we have found the root cause of the issue, we seem to be in a catch 22, where we can accommodate Outlook users or iPhone users connecting via IMAP. Of course we are working on a fix that can make it possible to accommodate both groups of users. Updates and news about the issue will be posted here in this blog.

If you need to read mail and list mailfolders on your iPhone before we have fixed the issue, there are at the moment two workarounds:

  • You can change your iPhone to connect via ActiveSync. This will require that you have Mobile Connectivity enabled in your subscription.
  • You can set your web client to use the new responsive skin, and then open the web client in a browser on your iPhone.

Should you have any questions or concerns in this context, then please contact Support.

The Kolab Now Team thank you up front for your patience.

Outlook and return options to LSUB

Posted on: January 9th, 2019 by

A while back, users started to experience issues with IMAP LIST Extension for Special-Use Mailboxes. This to a level where a decision was made to temporarily suspend supporting Special-Use at Kolab Now.

Lately we have found ways to get around the problems that were present back then, and over the change of the year we introduced an update that, among other great improvements, contained these solutions and re-enabled the Special-Use.

Unfortunately, meanwhile Microsoft has also updated Outlook, and their update has changed the return options that Outlook is using with the LSUB command on the IMAP server.

This has caused issues for some users, who connect Outlook to Kolab Now via IMAP. Those users are suddenly not able to see some of their folders and mails in Outlook. The folders are perfectly visible in the web client and in other IMAP clients like mobile clients, Mac Mail and Thunderbird.

While the RFC compliance issue (the LSUB command does not accept a client specifying RETURN options) certainly has been made visible by Microsoft changing the behavior of Outlook, inversely Kolab Now providing an update to the benefit of all other clients has suddenly shown the related Outlook behavior to be faulty.

The root cause of the issue can be narrowed down to the expectations from Cyrus IMAP while parsing the LSUB command. Besides filing an upstream ticket, Kolab Systems has engaged in this issue and is contributing a fix to the Cyrus IMAP code. This fix is now going through test and QA, and should be ready to be deployed to Kolab Now soon.

If you are one of the users, who has problems because you are connecting Outlook to Kolab Now via IMAP, then you can work around the issue by – either using another IMAP client – or by connecting your Outlook to Kolab Now via ActiveSync, until the fix for Cyrus IMAP is ready and deployed.

If you have any questions or concerns in this context, then please contact support@kolabnow.com.

Our statistics for 2018

Posted on: December 31st, 2018 by

Our terms of service state there’s basically no way for anyone to get any access to your data without us also being able to talk about the fact it happened, and further down nested in our legal framework outline do we have a list of 3 general types under which individual requests could be filed.

I recall that some place, we also promise to at least publish the statistics. I don’t recall where, but I seem to remember we have. In any case, here’s our summary for 2018.

A New Gregorian Year, A New Responsive Skin

Posted on: December 29th, 2018 by

The change of the year is always a good opportunity to look back at what has happened, and to make changes for the future. Earlier we have been writing about the work put into the Responsive skin (elastic skin) and it’s now time to enjoy the result we got out of the work that was done.

A version of a responsive skin was available on beta.kolabnow.com/apps for a while, but now it has finally passed QA, and is made available for all Kolab Now users.

Our October Silence?

Posted on: November 7th, 2018 by

Hi there,

I just wanted to provide you with a quick note that our blog roll’s “October silence” is nothing but just that. Some of us became a father to a son, have needed to deal with some citizen/resident paperwork, some of us choose to entertain the fresh snowfall way up the Alps, others took some vacation time, and such and so forth.

In the all-work-no-play area, I think we’ve figured out webmail decryption/signing, a responsive skin to be made available to mainstream Kolab Now, new exciting service venture definitions even though still under development, and we have now been able to deal with our midterm election anxiety (albeit November 25th could incur some implications domestically).
