spacemacs in java mode, moving the mouse over an email address displays in the modeline the text
mouse-1, C-c RET: mail this address. And if I click on it, a blank email sending form is opened in emacs (strangely enough that doesn't happen in haskell mode or fundamental).
My issue is that while I don't use the mouse much when using emacs, I often use it to focus the emacs window. And if there's somehow an email address exactly where I click, I open that email compose buffer, which is never what I want, because (at this point) I don't use emacs for email sending.
How can I disable that "click to compose an email" feature?
