Well, yes, this would be very helpful if I just had some email address 
I wanted to generate a mailto from. My problem is that the email 
addresses are scattered throughout the text like this:

$text=	"This is the content of my website.
		More stuff ...
		If you want to contact me, write to: myemail@myserver.de
		You can also write a letter to ...";
$smarty->assign("text",$text);

So I think I HAVE to use some regex_replace in a custom modifier. So 
here is my problem again: The function I defined for the callback 
doesn't get called.
