[Answered ]-Emailing to new top-level domains (TLDs) in django

I would suggest you subclass EmailField and substitute its set of default_validators with a custom validator that also supports the new top-level TLDs.

The default validator is django.core.validators.validate_email which in turn points to an instance of EmailValidator, which obviously you will have to subclass as well, and supply an instance of this subclass as the only item in default_validators attribute of your EmailField subclass.

You may want to have a look at the newer implementations of EmailValidator which not only supports TLDs ranging form 2 to 63 characters in length, but also a whitelist parameter that allows you to inject at custom list of valid domains.

Or, off course, if you prefer just upgrade to a newer Django version. I’m not sure exactly when the support for longer TLDs was added, but I’m sure you could figure that out by looking at the release logs or browsing the source.
