Trojitá is a free software IMAP and SMTP email client developed using the Qt C++ library. The design goals of the maintainers are to develop a fast e-mail client which respects open standards, is cross-platform and uses the available resources very efficiently.
Trojitá offers to manage contacts in the abook format, as introduced by the text-based user interface abook addressbook program.
In Autumn 2012, Trojitá became a part of the KDE community.
