Keeping mail on a local machine does not make sense when working across a large number of different (vitual) devices. As a GoogleApps user I have long preferred browser based mail client as my default.
Unfortunately this is not yet a very straight process on most Operating Systems and Ubuntu is no difference.
Edit: all the commands need to be run with root privileges. so either run “sudo su” or prefix all with “sudo ” (thanks to Paul for the comment below)
Remove Evolution (thanks to Grant Likely for the comment below)
apt-get remove evolution evolution-indicator
apt-get install gnome-gmail
Create entry for gnome-gmail using your preferred text editor and copy the following into the created file:
vim /usr/share/indicators/messages/applications/gnome-gmail #insert this line /usr/share/applications/gnome-gmail.desktop
Edit this file: /usr/share/applications/gnome-gmail.desktop and add the following line:
Update desktop database for Gnome Gmail to be recognised as an email program:
Go to System Settings –> Preferred Applications and choose gnome-gmail as the default e-mail client
Log out for the changes to the indicator to take effect (or kill gnome-indicator process).
