I have a script which sends an email to a client with a link in it once paypal has verified payment. This is all using the IPN function. When a purchase is made I recieve an email from firstname.lastname@example.org letting me know that the purchase has been made and a copy of the email sent to the purchaser. However the email is never sent to the purchaser giving them a link. I have purchased this script from a company that specilizes in this and they did the install. They said they have hundreds of these opporating with no problems and they cant figure out why mine isnt working. They mentioned that the server I am working on could have some security setting that are keeping it from sending out an email. I have installed the PHPmaillist offered by VodaHost in the fantastico area and it will not send out a verification email to the user either. Could be a different issue all together and I am not concerned with that immediatly but thought it was worth while info because it has the same problem and it could be related. any help appreciated.
