It's my pleasure to announce that version v0.2.9.3 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.

Most of the changes in this release fix bugs and improve IMAP interoperability, but we've got a few GUI improvement as well, like better indication of mailboxes containing "recent" messages.

Changes since version v0.2.9:

  • Visual indication for recent messages in mailboxes and threads with unread messages
  • Drag and drop of messages between folders
  • Improved threading
  • IMAP bug fixes and relaxed parsing for broken IMAP servers
  • Greater unit test coverage

xTuple integration

This version is included in the release candidate of the new version of the xTuple business management software. It is a first real-world deployment of Trojitá, manifesting its versatility, robustness and reliability.

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 v0.2.9.3, 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 KWest GmbH. and OpenMFG LLC, dba xTuple for their support in delivering the exciting new features of Trojitá. Another acknowledgment goes to the helpful folks at the #qt IRC channel and the qt-interest mailing list and also to everybody who reported an issue with Trojita or tested it against another IMAP server. A big thanks goes to the following people who have contributed patches to Trojitá: Benson Tsai, John Rogelstad, Andrew Brouwers, Gil Moskowitz, Jiří Helebrant, Jun Yang, Justin J, and Tomáš Kouba.

All the best,
