Paypal DoDirectPayment AND Pay by Paypal IPN issue

[mallsop]

So paypal is sending emails saying ipn transactions are failing, yet all transactions are working.

I have Paypal DoDirectPayment (for credit cards) AND Pay by Paypal IPN (for paypal accounts) in use. 

This is what I think is happening. 

If you have Paypal DoDirectPayment AND Pay by Paypal IPN, the DoDirectPayment will send to you IPN too, but mostly empty, to be ignored.

Or am I missing something?

Here is the email,  (real url not shown).

==start==

 'We are contacting you in regard to your #nd email titled "PayPal Instant Payment Notification Warning" which states:
>"Please check your server that handles PayPal Instant Payment Notifications (IPN). IPNs sent to the following URL(s) are failing:
>
>http://www.mywebsite.com/index.php/cart/ipn/
>
>If you do not recognize this URL, you may be using a service provider that is using IPN on your behalf. Please contact your service provider with the above information. If this problem continues, IPNs may be disabled for your account."
>

==end==

I found out later the error was 500 internal server error on my end.

The CC would post back to my ipn url and the PHP page I had created had an error. (No human sees the page).

I fixed the typo and the paypal transactions were not longer complaining (used to say retrying now says sent).

mallsop, thank you very much for posting your question and resolution.

I've encountered a similar problem and received the same email, but am not sure how to fix the issue.  What typo did you know to fix?  And which PHP page should I be looking for?  In my situation, would it happen to be this one?

Unfortunately, I don't know much about fixing server issues, so thanks in advance for any help you can offer!
