Mozilla Thunderbird is a free, open source, cross-platform email and news client developed by the Mozilla Foundation.
ISO standard date format
If you want the ISO standard date format (YYYY-MM-DD), then you can follow the date setting guide for Ubuntu.
Mimick Gmail
If you're migrating from Gmail, use Gmail on the side or just like the way Gmail works, you might want to change Thunderbird to work more like Gmail.
Keyboard shortcuts
How to set up Gmail-like keyboard shortcuts (inspired by a Teleogistic blog post):
- Install keyconfig
- Edit (or create if needed) the prefs.js file in the profile folder and add the following:
user_pref("keyconfig.main.key_killThread", "][I][");
user_pref("keyconfig.main.key_markJunk", "shift][!][");
user_pref("keyconfig.main.key_markReadByDate", "meta shift][D][");
user_pref("keyconfig.main.key_markThreadAsRead", "meta shift][R][");
user_pref("keyconfig.main.key_newMessage", "][C][");
user_pref("keyconfig.main.key_newMessage2", "meta shift][N][");
user_pref("keyconfig.main.key_nextMsg", "][J][");
user_pref("keyconfig.main.key_previousMsg", "][K][");
user_pref("keyconfig.main.key_reply", "][R][");
user_pref("keyconfig.main.key_replyall", "][A][");
user_pref("keyconfig.main.key_toggleMessagePane", "][V][");
user_pref("keyconfig.main.xxx_key74_SwitchPaneFocus(event);", "][D][");
user_pref("keyconfig.main.key_archive", "][Y][");
