Q: I have a client who is setting up a PayPal account so that she can sell e-books on her website
 
A: AFAIK PayPal doesn't support autoresponders, they stay out of the fulfilment end.
 
While you can use a straight download link there is a potential risk of the link being misused. It's probably worthwhile using something that sets up one-off protected links for each sale.
 
If your client has their site set up on a CMS like Joomla or Drupal they may be able to find a plug-in extension that will support fulfilment. I have done custom forms in Joomla that do something very like this.
 
There are may PayPal fulfilment scripts out there for simpler websites. I've heard good things about E-Junkie  who provide a packaged service for $5 a month for up to 10 products. I've also used Vibralogix'
LinkLok PayPal  successfully - this costs a once-off $29.95 but you have to do more installation and maintenance yourself, any webmaster should be able to set it up easily enough.
 
Best wishes
