Help Setting up Mailing list to recieve PayPal email details

[jj_glow]

I want to set up another mailing list for customers that subscribe to our monthly discount subscription offer. I will be using e-junkie and PayPal to complete this task. ejunkie can organize this for me. Here are the details I have from them:
 
How to integrate my site with your service?
All the transaction data can be sent to script on your server in the background. To enable this behavior, please set "This product requires: Information" while adding or editing your product.

We will POST all the IPN variables (given below) we receive from PayPal to this "Information URL"

payer_email
txn_id
first_name
last_name
item_number
payment_status
item_name
for complete list of IPN variables, please click here.

If it's a cart transaction, all the cart data from PayPal will sent as it is. Following two product specific variables will be added by E-junkie.

item_cart_position
item_number
Following variables are also sent, which contain information from your E-junkie profile and your E-junkie product entry.

from_name
from_email
expiry_hours
max_downloads


Could  someone help me with how I might set this up. Do I need to do something with a cgi script? I am willing to pay for support - I just want to get it done quickly. Can anyone help me out? Are there instructions as to how I might proceed?

Greetings,

It looks like your shopping cart will post your buyer information to the URL of your choice.  At that URL it would be very easy to set up a script to add the user to ListMail.  For example, you can add a user using just a few lines of PHP code as mentioned at the following URL:

http://listmailpro.com/forum/index.php?topic=1160.0

I would handle and support such a script for as low as $25 sent to paypal@listmailpro.com (submit all needed info to http://listmailpro.com/support?t=other) Let me know if you need me.

Regards
