Question about HTML area

Good morning from Gran Canaria.

I have an HTML area with this dataProvider:

	htmlContacto='<html><body style="text-align:center">\
	    <p><a href="http://www.galsaninformatica.com" target="_blank">http://www.galsaninformatica.com</a>
\
	    <a href="mailto:info@galsaninformatica.com">info@galsaninformatica.com</a></p>\
	    <p>C/. Graciliano Alonso, 38
\
        35110 - Vecindario - Santa Lucía de Tirajana
\
        España
\
        Teléfono +34 696471939</p>';

When I click on the site link it is properly shown in the browser, but clicking on the mail link does not open the mail client. Do I have to do anything else?

Thanks in advance.
