[enum-wg] ENUM-capable email client?

All,

there is a Firefox ENUM plug-in (currently for Win only) available at:

http://www.falb.at/

that resolves enum:[E.164 number] to an URL in case such web service is 
specified in the respective ENUM zone to that very E.164 number.

E.g., with this plug-in, a click on enum:+43780325228 would get you to 
Juergen Falb's homepage, too.

My question is: is anyone aware of a similar extension or even built-in 
function of a mail client, so that an E.164 number would be resolved to 
an email address?

Best regards,

	Carsten Schiefner
