Hi there,
Currently the whitelist in version 2.0.0 is case sensitive. I had a customer whose domain was entered in the whitelist as "Zaaaa.com", but when he tried to create an account with "zaaaa.com" it blocked his registration.
Once I added the domain as zaaaa.com, it worked for him.
Is there any possibility of making a future version case insensitive for domain names for the whitelist? Since DNS is case insensitive, it only makes sense that this plug-in's whitelist be case insensitive as well.
Thanks,
Eric
