I’ve made a quick but extensive research for a webmail software to put on my server(s) whose the most important feature should have been simplicity of maintenance and use over completeness and number of features.
My effort resulted in the following list ordered by the previous constraint:
- RoundCube (beta software)
- uebimiau (also look here, apparently no more maintained)
- IMP (based on Horde framework, included with Plesk web control panel)
- OpenWebMail (not installed but famous enough)
So my choice fallen on RoundCube because, even if its beta status, it’s easily installed (even with multiple domains), has all the fundamental features for your users and is lovely in appearance (web 2.0 style).
There are many more webmail applications not cited here and I discarded it mainly because they seemed too old or not “trustable” at first sight (so I could have made some mistakes, sorry.)
What is the best web mail solution in your opinion?
