Trojitá released

Trojitá has been released. This is a bugfix release -- details inside.
Added by Jan Kundrát almost 9 years ago


It's my pleasure to announce that version v0.2.9.4 of Trojitá, a fast and lightweight IMAP e-mail client based on the Qt library, is now available. For more details of what Trojitá is and who should use it, please see below.

Changes since version v0.2.9.3:

Most of the changes in this version happened under the hood. You won't likely see any user-facing changes, but the operation is more robust and quite a few crashers got fixed. The application will also by default create a debug log which is very beneficial when diagnosing possible issues; see the IMAP -> Logging menu for details.

The 0.3 will be much more interesting, but to get there, there's still quite a lot of stuff ahead.

What is Trojitá

Trojitá is a very fast and lightweight IMAP e-mail client written using the Qt library.

What could make Trojitá interesting for you:

  • It's a pure Qt4 application with no additional dependencies; it builds in two-and-half minutes on a five-year-old laptop
  • Robust IMAP core implemented using Qt's Model-View framework
  • Standards compliance is a design goal
  • On-demand message list and body part loading ("lazy loading")
  • Offline IMAP support
  • Support for bandwidth-saving mode aimed at mobile users with expensive connection
  • IMAP over SSH -- instead of going over an SSL socket, the server could be accessed via SSH
  • Safe and robust dealing with HTML mail

Please note that the "message sending" and "message composing" features of Trojitá are a bit lagging at this point and therefore it is not recommended to use Trojitá for these tasks apart from testing.

Certain features of Trojitá depend on the IMAP server's functionality. Trojitá is written from the bottom-up as an IMAP client and is designed around its feature set. For example, threaded message viewing (ie. "conversations") is supported only if the server implements an appropriate extension for now.

Trojitá is under heavy development, features are added on almost daily basis and the codebase is rapidly maturing. Certain useful features are still missing, there is no support for searching, for example. We have tickets opened for these, so please Cc yourself at the task tracker if you would like to follow the progress here.

Finally, as with any software, Trojitá has some bugs which are already known and reported in the issue tracker and some which are still waiting for discovery. That said, it is safe to use to for reading mail. I've been doing that for several years on a production account, and I have never lost a mail with Trojitá. Please do not send e-mails with current version, though, as it is known to produce non-standard messages in certain circumstances.

Where I can get it

Our web has all the required information, but if you are impatient and just want to grab the tarball for v0.2.9.4, download from Sourceforge:

Trojitá is known to work on Linux, Mac OS X and Windows. It should also run on all platforms supported by Qt. Optimizations for mobile devices and the Maemo/MeeGo are in the works.

Reporting bugs and wishes

Please use this Redmine portal to report issues with Trojitá. If you do not want to be bothered by a registration, please at least send bug reports via e-mail or report them at the #trojita IRC channel on Freenode.


Trojita could always use more people in the community. Areas in which people are needed most, as well as general guidelines about how we prefer to work are documented at Contributing_to_Trojita.

The IRC channel is #trojita on, the mailing list is (moderation required for non-subscribers, archived at various places etc).


I'd like to thank the helpful folks at the #qt IRC channel and the qt-interest mailing list; they provide an excellent support. A huge thanks goes to everybody who reported an issue with Trojita or tested it against another IMAP server. Finally, I really appreciate the help from Benson Tsai, John Rogelstad, Andrew Brouwers, Gil Moskowitz, Jiří Helebrant, Jun Yang, Justin J, and Tomáš Kouba, who have contributed patches to Trojitá.
