One area on the Linux desktop that remains surprisingly conservative is email – email clients and webmail alike. While most if not all of the formats and protocols used are true open standards, you would think there could be a broad range of clients and webmails for Linux out there. Let me correct that: webmails are in a league of their own and I will not enter the webmail vs. email clients discussion. Many things are changing in that field, but one must differentiate between the actual email service, like GMail, your corporate mail, the webmail software (Roundcube, Horde, Citadel, Squirrel, etc.), the groupware platform (Kolab, Blue Mind, OBM, eGroupWare, and many others) and what lands and gets edited, if you’ve chosen so, in your email client, meaning the actual software program running distinctly from your web browser and handling anything from emails to calendars and contacts. Today I will focus on the email clients on the Linux desktop. I do not pretend that my list is exhaustive; it is but a personal selection; I have also excluded email client such as Mutt, mu4e, VM, RMail, Ner, Wanderlust, etc. as I will only be speaking of graphical email clients on Linux, at least the ones I’ve tried.
