Jabber spam has become a huge problem over the last one or two years. Spammers register thousands of accounts on hundreds of public servers, and then send masses of messages to real and guessed Jabber addresses. The yax.im server operators are committed to fighting XMPP spam and helping others do so as well. In the last two weeks, yax.im automatically blocked 46996 messages from 14293 different accounts registered on 282 different servers.

There is a new yaxim release, fixing the CVE-2017-5589 security vulnerability. PLEASE UPGRADE NOW!. The vulnerability allowed attackers to make messages appear as if they were sent by somebody else:

The release also provides a number of long-awaited improvements like Easy XMPP, Group chats, Android Auto, a new design and much much more.

In the last three months, it was not possible to register new accounts on yax.im. This issue has been resolved now.

Currently, the yax.im service is experiencing connectivity problems (“remote-server-not-found” or “connection-timeout” on server-to-server links, “Unable to resolve yax.im” on clients) due to a DNS problem.

To support DNSSEC, we are moving the yax.im and yaxim.org domains to a different set of nameservers. It looks like the old nameservers for yax.im stopped resolving the domain before the 72h transition period was over; a support ticked has been opened for this. Please bear with us (or flush your resolver cache) until the issue has been fixed.

yaxim’s stated first goal is security. Unfortunately, there are days when you realize you failed hard at reaching that goal. All versions of yaxim before 0.8.8 are vulnerable to a Man-in-the-Middle attack, where an active attacker can redirect and read all your traffic by using a valid SSL certificate for his own server.

Please update immediately to 0.8.8 (ChangeLog, commit history)!

A new release of yaxim, 0.8.7b, has been made public today (ChangeLog, commit history).

The 0.8.7 release was timed for the XMPP Summit, and contained some little issues, which have been fixed since then. Many thanks go to the sedulous testers who contributed detailed problem reports.

Update: the following text was posted on April Fools’ day, 2014. yaxim (as well as yax.im) remain a little private project of its administrators, and there are no plans to get acquired, especially not by the military-industrial complex. Nevertheless, we encourage everyone with the respective capability to run their own servers for themselves and their friends!

In the last months, several big takeovers happened in the Instant Messaging world. Facebook bought Instagram and WhatsApp (but failed to get Snapchat), Rakuten got Viber, and Tango was bought by China’s Alibaba. We at yaxim used the exciting growth that followed the start of the yax.im service to unite with Booz Allen Hamilton, a strong partner that greatly values our assets.

A new version of yaxim, 0.8.7, has been released today (ChangeLog, commit history) right in time for the XMPP Summit. Download 0.8.7 now!

This release comes with some long-awaited features, like Stream Management, proper roster handling, improved error display and better internationalization.

With great pleasure we want to announce a new public service brought to you by yaxim.org - the yax.im (read: Yaks’ IM) public XMPP server.

To register with it, open your XMPP client (e.g. yaxim), choose a JID of your liking that ends with @yax.im, like test@yax.im and activate “Register new account”.

Up-Update: the following text was posted on April Fools’ day, 2013. There is no commercial version of yaxim, and the only money making plans we have is to add donation support, sometime in the far future.

After almost four year of development, we are proud to announce that yaxim, our Open Source XMPP client, is sufficiently mature to fulfill even the needs of large corporate customers. And like with any project that grows from your garage to become a viable product, the day comes when its commercial future needs to be set.

Starting Tuesday, yaxim will adapt its pricing to the competitive levels set by the Mobile Network Operators with their new Rich Communication Services (also known as joyn™). However, there is no need to worry. For most of our loyal customers, the free Basic plan will be more than sufficient. For other customers, we offer the Standard, Advanced and Professional plans at reasonable monthly rates.
