connection error (failed to reach the server)
by Bob Miller 23 Jun '15

23 Jun '15

Hello, it was brought to my attention a few months ago that a mac user was seeing the following pop up dialogue box in roundcube with some frequency: connection error (failed to reach the server) At the time, I was chasing a problem with apache where hundreds of connections would open up within a matter of a minute or two, maxing out the allowed connections, and causing roundcube to be unavailable for about 1 minute a few times a day. Didnt' take me long to figure out the IP causing the apache problem was the same user reporting the error pop up. I never did figure out the root of the problem, but I suspected it had to do with the self-signed certs and the CA not being installed on the client's mac. A while later, another mac user started reporting the same error popping up, and I saw the same spike in http connections from this user's IP addresses. Investigated more, got the CA cert installed on this mac, didn't fix the problem, ended up again with no solution. Reloading apache always worked, but it was hard to be on hand whenever the connections spiked, so I wrote a little script that checks the number of connections and reloads apache when it gets over 400 connections. That solved the apache problem (bubblegum, I know), so I called it a mac anomaly put it on the back burner. the error popup didn't actually stop anything from working, just had to click it closed every few minutes, and my customers were amiable to doing just that. Over the last couple of months, I have learned/seen that the same popup happens on ipads and windows computers as well. I just worked on one windows computer where the popup happened in chrome/firefox/IE, with the CA installed so there is no certificate error. Conversely, I use roundcube every where I go on a wide variety of computers, and I do not see this error very often, if ever (can't remember seeing it while logged into my personal account right now). I definitely cannot reproduce it on my ubuntu machine in the office. Best as I can tell on google, the error indicates an http connection failure, but nothing actually fails to work. I can find nothing in the roundcube logs nor the apache logs, which I suppose is expected if the client is failing to connect to the server. The internet connections in my part of the world lack the speed the rest of the world sees; for example and average business/residential connection has a 512Kbps or 768Kbps upload speed, but surely just navigating in roundcube wouldn't flood that? The computer I was just working on is a few years old and a tad underpowered by modern standards, but for a minimal install of windows 7 it isn't sluggish, and cpu/RAM usage don't spike when roundcube is open. And the spike in http connections to the server did not happen, so I am not longer certain if that is related. Does anyone have a suggestion on how I might track the cause of this annoying popup? Or at least cause it to stop popping up all the time? -- Computerisms Bob Miller 867-334-7117 / 867-633-3760 http://computerisms.ca

Reply to own messages broken...?
by Michael Heydekamp 23 Jun '15

23 Jun '15

Hi, just did set up some mail accounts for a new user and did realize that replies to an own message are being sent to the own address of the original sender rather than to the address of the original recipient. This still works: ----------------- 1) > From: Michael Heydekamp <michael(a)mydomain.de> > Display name: Michael Heydekamp > Email: michael(a)mydomain.de This does not work: ------------------- 2) > From: Michael Heydekamp <michael(a)mydomain.de> > Display name: Michael Heydekamp xxxxxx - xxxxxxx xxx xxxxxxx > Email: michael(a)mydomain.de 3) > From: Michael Heydekamp xxxxxx - xxxxxxx xxx xxxxxxx <michael(a)mydomain.de> > Display name: Michael Heydekamp xxxxxx - xxxxxxx xxx xxxxxxx > Email: michael(a)mydomain.de 4) > From: =?UTF-8?Q?Michael_Heydekamp_xxxxxx_-_xxxxxxx_xxx_xxxxxxx?= > <michael(a)mydomain.de> > Display name: Michael Heydekamp > Email: michael(a)mydomain.de Where "Display name" and "Email" are the relevant entries under Settings/Identities, and "From:" is the From header of the message. According to Example 2) above, Roundcube seems to check for the display name as well...? IMO, it shouldn't do that and check for the address only. Example 3) is strange: Display names are identical, nonetheless the routine fails. Is the display name too long? Example 4): Not sure if folded headers are the problem here. Fix appreciated, as the user in question did already send a few messages to himself, relying on a working Reply-to-own-messages routine (and not realizing the wrong recipient address).

Roundcube Next is coming and we need your help!
by Thomas Bruederli 18 Jun '15

18 Jun '15

Dear subscribers What started with the hypothetical question, "how would we implement Roundcube if we could start over again?" [1], has now grown into a concrete plan how to create the responsive, fast and beautiful successor of Roundcube. It has become clear that the architectural changes necessary for this are way too big to be applied to the current Roundcube codebase without breaking the compatibility in a major way. That's why we're planning to define Roundcube One as feature complete and focus on a new core engine for the future Roundcube webmail application. In order to make than happen, we can reply on long time partners who supported Roundcube already in the past. Kolab Systems has offered to drive this project by contributing their well established software development capabilities and dedicate additional developer power to help us get the work done. In addition to that, the folks from Kolab Digital in London are going to share their expertise on the UX and design part of it. Two major goals are important to us: Besides improving the core technology and modernizing the UI, we also aim to move some of the groupware features we currently see in the Kolab suite into Roundcube itself and make them available for other backends. And we'll certainly provide a migration path to existing Roundcube installations. So to enable us to achieve these high stake goals together for Roundcube Next we proudly announce our crowdfunding campaign at Indiegogo. Go to https://roundcu.be/next and back us if you can or help us spread the word about it. Your websites, blogs and social media channels can help us reach more people. Or if you're working for, or are a customer of, an ISP who's already using Roundcube, please forward this campaign to your product manager. Let's challenge today's email and create the most awesome webmail application people deserve to communicate freely using systems and services they can trust. The next Roundcube will of course again be 100% open source and made available to everybody. This is your chance to contribute to the success of free software. Many thanks to all of our past, current and future supporters! Sincerely, The Roundcube Dev Team [1] https://roundcubeinbox.wordpress.com/2014/09/12/roundcube-next-if-we-would-…

Text signature vs. HTML signature
by Michael Heydekamp 18 Jun '15

18 Jun '15

Hi there, although I do really hate HTML messages (and their multipart/alternative incarnations, as they're most often misformatted), there's sometimes no way around it to use them. Especially if you're starting an own business and need to compose messages with HTML signatures, including a logo and this kind of stuff. So I expected Roundcube to be able to create a) a signature in plain text format for text messages, and b) an alternative signature in HTML format for HTML messages - for the same account, of course. Therefore, today I played the very first time with the toggle "HTML signature". But I really don't get what this option does (or should do). Let's say I have this plain text signature ("HTML signature" de-selected): -------------------------------- > -- > Michael Xxxxxxxxx > Tel.: +49-(0)211-xxxxxxx > Mobil: +49-(0)172-xxxxxxx > eMail: michael(a)xxxxxxxxx.de > WWW: http://www.xxxxxxxxx.de -------------------------------- If I now select the toggle "HTML signature" and de-select it again, the following plain text signature is being returned: ---------------------------------- > -- > Michael Xxxxxxxxx > Tel.: +49-(0)211-xxxxxxx > Mobil: +49-(0)172-xxxxxxx > eMail: michael(a)xxxxxxxxx.de > WWW: http://www.xxxxxxxxx.de [1] > > Links: > ------ > [1] http://www.xxxxxxxxx.de ---------------------------------- Not only that there is an IMO senseless additional link being created, also the blanks after "Tel." etc. are gone, so the contacts are not properly left-aligned anymore. If I do the same again, the following plain text signature is being returned: ------------------------------------------ > -- > Michael Xxxxxxxxx > Tel.: +49-(0)211-xxxxxxx > Mobil: +49-(0)172-xxxxxxx > eMail: michael(a)xxxxxxxxx.de > WWW: http://www.xxxxxxxxx.de [1] [1 [1]] > Links: > ------ > [1] http://www.xxxxxxxxx.de [1] > > Links: > ------ > [1] http://www.xxxxxxxxx.de ------------------------------------------ Even more senseless links! And so on... As I said, I don't get it. What's that for...? Can somebody explain? The creation of the body of HTML messages seems to even worse, but that's a different issue for a different thread then. Any help appreciated. Cheers, -- Michael Heydekamp Co-Admin freexp.de Düsseldorf/Germany

Dear Roundcube users We just published updates to both stable versions 1.0 and 1.1 after fixing many minor bugs and adding some security improvements to the 1.1 release branch. Version 1.0.6 comes with cherry-picked fixes from the more recent version to ensure proper long term support especially in regards of security and compatibility. The security-related fixes in particular are: - XSS vulnerability in _mbox argument - security improvement in contact photo handling - potential info disclosure from temp directory See the full changelog here: http://trac.roundcube.net/wiki/Changelog Both versions are considered stable and we recommend to update all productive installations of Roundcube with either of these versions. Download them from https://roundcube.net/download As usual, don't forget to backup your data before updating. And there's one more thing: Our crowdfunding campaign for Roundcube Next is still ongoing and has just been updated with more details of what we want to achieve. We'd much appreciate your support for this exciting new project. Please visit https://roundcu.be/next and spread the word about it.

Server Error: Unable to send command: A0009 UID EXPUNGE 18748
by Josep BSC 04 Jun '15

Hi all, I am posting here because when upgrading from RC 0.5.4 to RC 1.1.1 I am getting this error when I try to delete a message from Inbox folder, the rest works fine. Server Error: Unable to send command: A0009 UID EXPUNGE 18748 Even though the message is deleted from the mailbox, but it is quite annoying to have it there. It just weird that it happens only to the INBOX folder. With the previous version it worked fine, no error message was displayed.

Re: [RCU] Server Error: Unable to send command: A0009 UID EXPUNGE 18748

Hi Harald, I totally agree with you. But since this is only a barely used server and only accessible from within the company's facilities..... So, I assume that it is related with the Dovecot server, isn't it? Best regards.

External AD/LDAP server address book
by Diogo Vieira 25 May '15

25 May '15

Hello, I'm trying to add an address book from an external LDAP server for one of our clients in our shared roundcube installation. From what I could tell roundcube supports this[0] but I would like to know if I can filter that address book only to appear to clients in a specific domain. Is this possible natively? In case it isn't, would it be necessary/possible to create a plugin for roundcube? [0]: at least it seems so as per the "Configuring Roundcube" section of http://trac.roundcube.net/wiki/Howto_Config/Ldap Thank you very much for your attention, -- Diogo Vieira <dfv(a)eurotux.com> Programador Eurotux Informática, S.A. | www.eurotux.com

Server Settings prefs
by list＠airstreamcomm.net 19 May '15

19 May '15

Running Roundcube 1.0.4 and we didn’t notice this for a very long time but the “Server Settings” preferences section is not visible on our install. We looked on line but could not find anything, is there some configuration option to expose this to users?
