Address in mailbox given [] does not comply with RFC 2822, 3.6.2. when email is in a variable

Question

I have a correct email address. I have echoed it, but when I send it, I get the following error:

 Address in mailbox given [] does not comply with RFC 2822,          


        

Answer 1

 Mail::send('emails.activation', $data, function($message){
        $message->from('email@from', 'name');
        $message->to($email)->subject($subject);
    });

I dont know why, but in my case I put the from's information in the function and it's work fine.
