Email not functioning when entered in all CAPS

OK....I admit this is very strange but it happened.....a lot!

For some reason when some clients would place orders we would receive payment notification from PayPal but we would NOT receive (nor would our clients) the universal email "receipt" that contained all of the order details.

The only constant that we had between those that received our "receipt" emails and those that did not was the PayPal payment receipts. When we started to investigate we found that all of those that did NOT receive "receipt" emails were people that typed in all of their information in ALL CAPS versus Caps Lowercase.

We sampled about 1000 orders so it was a very good sample.

So....Why would someone submitting an order in ALL CAPS cause the universal email not to trigger?

Any ideas?

Thanks for all!

Good work, i was able to reproduce the same issue you are having when you enter all capital email address.

To fix this issue:

open the MailFormatting_PHP.php file which is located in your WA_Universal_Email folder and look for this line of code:

if ($testAddress != "") {

and right above it place this line of code:

$testAddress = strtolower($testAddress);

So you should have:

$testAddress = strtolower($testAddress);
if ($testAddress != "") {
