I'm trying to update store email addresses through the admin panel, but no matter what I do I keep getting the error; "Please correct the email address". There's nothing wrong with the email address. What's going on?
It looks like Magento is deliberately blocking a number of TLDs. This will also prevent customers from creating accounts and cost store owners money. I've found a fix on GitHub, but I'm not sure if I should be using it. Looking at the path, it looks as though it's modifying core which I don't want to do. Can someone confirm that installing this will fix the issue and won't be overwritten on the next update of Magento?
If it's been a bug for years, then there's obviously no will to fix it and I suspect that nothing I can say is going to make any difference. Will the following fix resolve the issue (the right way, not changing core)?
