Yes it is valid even if it does not exist yet.

I know that. Many gems use what I found : email_validator, validate_email etc …
But who cares !!! It is opensource and I am happy with it !! (a quote or a WWR vote may help me )

Thanks you all for your feedbacks !!

It seems that since this post has become quiet popular so we should create a project in github.

@jose I don’t know yet if I will patch the mail gem but it is a good Idea

The first step is maybe a gem (for backward compatibility) then pull request a patch to Mail gem.

If you want to follow the project status here is the github repository :

Nice! Have you considered providing a patch to the Mail gem that adds a valid? method to Mail::Address? This way, we could just use the valid? method instead of explicitly checking the dots or worrying about Treetop details.

This validator seems to allow multiple email addresses:

p = Person.new
p.name = “Test”
p.email = “test@example.com, test2@example.com”
p.valid? # => true

Is that intended?

haxney :
This method seems to fail for valid email addresses like

“name”

Also, treetop.domain doesn’t exist in my version of Ruby (1.9.2p290), and it seems like this would suffice (sorry, I don’t know how to input code to WordPress):

def is_valid_email?(e)
m = Mail::Address.new(e)
m.domain && m.address
rescue Mail::Field::ParseError => e
false
end

This method also has the advantage of returning the “addressy” part of the address (name plus domain), with any comments stripped.

Yep but a validation don’t need to return anything else than true or false. This piece of code was originally intended to rails application If you want some more features , it might be useful to create a gem upon Anyway for the most use cases, we do not type such rfc valid email like below in a text field (as in a signup form) “John Doe ” This email is valid and the mail gem can extract the user and domain part but iMHO this is not the purpose

As many want to make it a gem, it seems to be a good idea.
However I wonder how consistent it will be in a future since it relies on the “tree” private method
