PHP Email a list to user

PHP Email a list to user

I have a php script that has taken user input from a html page and created
a list. I want to be able to email that list to the user, and already have
the user's email address from the html page.
So far, when the user hits 'email me the list' I can get the program to
automatically open the person's outlook program. I want to be able to copy
and paste the list into the email document, or at least copy and paste the
link to the page where the list exists.
Any help would be appreciated.
Thanks
Andrew
EDIT:
HTML FORM:
<strong>Email Address</strong><FONT COLOR="#FF0000">*</FONT>:
<input type="text" name="emailaddress2"/>
<input type="submit" value="Submit"/>
PHP :
<a href="mailto:<?php echo $_POST['emailaddress']; ?>">Email me List</a>
(So basically I want the list pasted into the email)
