Invisible mailto: in org mode email links?

Out of the box in Emacs Org Mode, an email address example@example.com is not linked.

mailto:example@example.com is a working link but is ugly.

[[mailto:example@exa开发者_高级运维mple.com][example@example.com]] is an invisible mailto link because it shows only example@example.com but works like a normal mailto link.

How can I make all email addresses invisible mailto links?

To accomplish that automatically, you'd need to mess with the regexp matching inside of org.el. Specifically, looking quickly, it looks like you need to modify at least the org-make-link-regexps function. But out of the box, org-mode won't do this without some coding help.
