title: link to an email attachment
body: <p>Hi I am sending email attachments (using php) and would like to point out to the people that I send the emails to that there are attachments.
  I want to do this by displaying a link in the html body of the email, so all they need to do is click the link and there system will try and open/view the attachment. </p>
  
  <p>Does anyone know if this is this possible? 
  and if so any pointers/nudges in the right direction would be appreciated.</p>
