Set Domain Hosted Gmail as Default Mail Client in Ubuntu
I use gmail to host the email for corruptive.co.uk and just installed Ubuntu on a new laptop. In Firefox I want to use the right click menu to send links but Evolution is set in System>Preferences>Preferred Applications.

Mail Reader , Custom;
/home/mctt/open_mailto.sh %s
(replace mctt as needed)
The answer to how to change this is found here and subject to some geeky debate;

The answer is to follow this guide replacing the https://mail.google.com/a/corruptive.co.uk/
with whatever your domain is.
So then select Applications > Accessories > Terminal
gedit /home/mctt/open_mailto.sh
Copy and paste the following from Jeff Waugh
#Keep it short and sweet, people.
#!/bin/sh
FIREFOX=$(which firefox)
URL=$(echo $1 | sed 's#mailto:##;s#?#\&#;s#\&subject=#\&su=#i;')
$FIREFOX -remote "openurl(https://mail.google.com/a/corruptive.co.uk/mail?view=cm&tf=0&to=$URL)"
Save and close gedit.
Then in the Terminal give the script execute permissions;
chmod u+x ~/open_mailto.sh
Go and try it from Firefox.
