Please answer these questions before submitting your issue. Thanks!

What did you do?

If possible, provide a recipe for reproducing the error.
A complete runnable program is good.
A link on play.golang.org is best.

package main

import (
	"fmt"
	"net/mail"
)

func main() {
	_, err := mail.ParseAddress("John Doe ")
	fmt.Println(err)
}

What did you expect to see?

mail: no angle-addr

What did you see instead?

mail: missing phrase

According to rfc5322:
name-addr = [display-name] angle-addr
display-name = phrase

So, display-name is optional.

Does this issue reproduce with the latest release (go1.8)?

I think so
