Paypal IPN "email address not matched"

[flakrat]

I have the paypal IPN module installed and have the primary paypal email address entered into the module configuration. I buy something on my store, get redirected to Paypal site, complete the payment process and I don't get an order number.

Here's the output from the Paypal IPN modules log file (the only thing I modified in the output was to change the email address to MYUSER AT MYDOMAIN DOT COM, and yes in the log file they are identical).

Mon Oct 2006 17:26 -- IPN WARNING::Transaction email address not matched. From IPN = MYUSER AT MYDOMAIN DOT COM: From CONFIG = MYUSER AT MYDOMAIN DOT COM

Mon Oct 2006 17:26 -- IPN FATAL ERROR::Transaction did not validate

Any idea why it says the Transaction email address doesn't match?

Oh, and I'm using Zen 1.3.5 and host my own server on a T1 (i.e. I control the firewall) and don't seem to have any issues with people accessing my site via 443 or 80, and no issues accessing those ports from the server.

I'm also testing this against the live paypal server, not using the sandbox and haven't gotten it to successfully integrate on three purchases.

I tried setting both the http and the https URL in Paypals "Instant Payment Notification Preferences"

http://www.MYDOMAIN.com/ipn_main_handler.php
and
https://www.MYDOMAIN.com/ipn_main_handler.php

Both produced the same error about the emails not matching!

And I copied exactly (to the clipboard and pasted) the primary email address from Paypal's email setting page to my Paypal IPN module config page.

Sorry for so many updates, the forum won't let me edit my posts after 7 minutes, and these thoughts keep popping in my head.

Here are the two settings I have for my web servers iptables firewall.

-A RH-Firewall-1-INPUT -p tcp -m state -m tcp --dport 80 --state NEW -j ACCEPT
-A RH-Firewall-1-INPUT -p tcp -m state -m tcp --dport 443 --state NEW -j ACCEPT

This server is connected directly to the internet, is there anything in that config that would prevent bidirectional communications?

line 60 -- alter it like this:

    if (strtolower($postArray['business']) != strtolower(MODULE_PAYMENT_PAYPAL_BUSINESS_ID)) {

Thanks Dr Byte,

That worked. Is that a bug? If not, I'm confused why the original code has strtolower on one side of the test and not on the other. Shouldn't it be (like your suggestion) both strtolower or neither?

Now I just need to figure out why Paypal isn't auto returning. The click here to return to the merchants page works, just no auto return. Guess I'll give Paypal support a call on that.

Yes, it's a bug, which has been explained ad nauseum elsewhere, and is fixed in the next bugfix release 1.3.6, which is not yet released.

Thanks again. I promise that I searched the forums before I posted. As usual I must not have searched for the correct keywords.

Glad it's working for you !

(unfortunately, that bug is a result of PayPal's documentation saying one thing and then "doing" another thing )

Is this problem also in 1.3.2? My store was going fine, and now the IPN has stopped working, and just returns to the checkout_success after payment but no order - Vamoos!! Never seen again.
