33456	Make underscore in hostname error more explicit	kimsia	nobody	"Currently, the error message is simply

""The domain name provided is not valid according to RFC 1034/1035.""

Most tickets filed against this topic is about how underscores should be allowed. I agreed with Django's choice to invalidate underscores. 

https://github.com/django/django/pull/594 explains this clearly.

However, the error message can be clearer. 

I recommend when underscore is detected, simply make it more explicit

"" %r contains _ and that is not valid according to RFC 1034/1035."" % domain

Otherwise, ""The domain name provided is not valid according to RFC 1034/1035.""
