What is the proper way to escape user's name in the "To" email field?

I'm sending email from my Rails 3 application:

mail(
    :subject => "My Subject",
    :to => "\"#{user.full_name}\" <#{user.email}>",
    ...

But what happens if user entered his name as John "The Great" Doe? Obviously, this would break my quoting of the user's name. But would the email still be delivered? Should I somehow escape the user's name when used in the "To" email field? And if yes, how: double quotes, or backslashes, etc?

What you're really asking is how RFC2822 wants such things to be quoted. See:

http://www.ietf.org/rfc/rfc2822.txt

Note that quoting in general is a much more complicated problem than you may imagine -- quotation marks are only one of many problems you face.

That said, I would hope that Rails handles a bunch of this on your behalf -- it is commonly needed and complicated. (I am not a rails guy so I can't answer that for sure.)
