How to generate subject at runtime (Mailer2 Tag)

Hi,

I'm using Mailer2 to send automatic mail to some address.
I would like to generate automatically the subject passing a variable 
but I can't!

My code is:
<mt:mail
	from="[email protected]"
	subject="<% out.system(request.getParameter('titolo'));%>"
	server="mailServer"
	username="username"
	password="passwrod"
	background="false"
	type="multipart/alternative"
 >

I've tried both way to add a variable (scliplet and c:out tag) but 
nothing: the subject I get contains exactly the code I've put in the 
subject parameter.

Any idea?

Thanks

LuKe
