I'd actually suggest not doing even that.
There are search bots out there which will read all of the HTML generated by the page looking for e-mail addresses to spam. So even if you can't see the underlying e-mail address on the screen, the bot will find the underlying mailto:// link, grab the actal e-mail address, and your spam count eventually goes up.
I'd suggest doing something that is more likely only to be deciphered by a human, such as:
(The "dot" is a bullet character, though this editor requires a visible character also be typed after the bullet in oder to keep from deleting the bullet after a save. Too bad we can't edit the HTML directly. You could do something like [dot] as instead, though.)
or maybe even inserting an image with the address spelled out.
True, the human has to type in the correct address into their e-mail software to send the message rather than simply clicking on a link, but it should help keep your spam count down.
