XAMPP/osCommerce install. Email problems

[♥Skittles]

I finally decided to bite the bullet, and installed xampp on my computer. My previous experience with osCommerce was maintaining and modifying an existing account for a client.

 

I sell stock photography on my web site. To date, if you purchase an image, I email you the file. Last week, I had a designer ask to purchase an image that was only available as free wallpaper. He informed my that the ad agency he was working with would only purchase images if they could pay for them online and download them immediately.

 

We worked something out, but his words made me realize I could no longer put off integrating osCommerce into my site. Not having immediate download functionality almost cost me a $150 order. And there is no way of knowing how many other orders never happened because I didn't have that functionality. Now that's some incentive!

 

I have had massive issues just trying to install osCommerce. Apparently there is something not right on my server. So I decided to install osCommerce on my computer, using xampp, to work on site changes while my host clears up the discrepancies on the server.

 

Installing xampp was relatively easy, though I would have appreciated some install notes that told me what to expect. Then following the instructions available with Vger's Quick Install Guide, I had the basic osCommerce shop up and running in just a few minutes.

 

Now I am in the process of installing the Download Controller contribution and I've discovered I can't send mail.

 

I don't actually need messages to leave my server. But I do need for osCommerce to believe the message has been sent successfully.

 

Everytime osCommerce tries to send an email, I get the following error messages:

Warning: mail() [function.mail]: SMTP server response: 553 We do not relay non-local mail, sorry. in D:\offline\xampp\htdocs\mysite\catalog\admin\includes\classes\email.php on line 522

 

Warning: Cannot modify header information - headers already sent by (output started at D:\offline\xampp\htdocs\mysite\catalog\admin\includes\classes\email.php:522) in D:\offline\xampp\htdocs\mysite\catalog\admin\includes\functions\general.php on line 22

 

I've tried tinkering in the sendmail.ini, and tried changes to the email.php include files, but without success. Obviously I'm in over my head on this one. I could really use some expert help setting up the sendmail function in xampp.

 

I am fairly computer literate, but linux/apache challenged.

 

Thanks in advance.
