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

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, 3.6.2. 

Why? I use laravel (swift mailer) to send email:

$email = [email protected]

and then when I send it, the error is thrown.

But if I directly use the string, it sends it.

Here is the block:

 Mail::send('emails.activation', $data, function($message){
            $message->to($email)->subject($subject);
        });
                ->with('title', "Registered Successfully.");

I have faced the same problem and I have fixed. Please make sure some things as written bellow :

   Mail::send('emails.auth.activate', array('link'=> URL::route('account-activate', $code),'username'=>$user->username),function($message) use ($user) {
                        $message->to($user->email , $user->username)->subject('Active your account !');

                    });

This should be your emails.activation

    Hello {{ $username }} , <br> <br> <br>

    We have created your account ! Awesome ! Please activate by clicking the   following link <br> <br> <br>
   ----- <br>
      {{ $link }} <br> <br> <br>
       ---- 

The answer to your why you can't call $email variable into your mail sending function. You need to call $user variable then you can write your desired variable as $user->variable

Thank You :)

Your email variable is empty because of the scope, you should set a use clause such as:

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

I had very similar problem today and solution was as it is..

$email = Array("Zaffar Saffee" => "[email protected]");
        $schedule->command('cmd:mycmd')
                 ->everyMinute()
                 ->sendOutputTo("/home/forge/dev.mysite.com/storage/logs/cron.log")
                 ->emailWrittenOutputTo($email);

It laravel 5.2 though...

my basic problem was , I was passing string instead of array so, error was

->emailWrittenOutputTo('[email protected]'); // string, we need an array

Its because the email address which is being sent is blank. see those empty brackets? that means the email address is not being put in the $address of the swiftmailer function.

These error happen when the $email variable is empty or sometimes when the mail doesn´t exists, try with an existing mail

The only solution worked for me is changing the following code

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

Your problem may be that the .env file is not loading properly and using the MAIL_USERNAME.

To check if your .env file is loading the email address properly add this line to your controller and refresh the page.

dd(env('MAIL_USERNAME') 

If it shows up null try running the following command from command line and trying again.

php artisan cache:clear

Try this.

Mail::send('emails.activation', $data, function($message) use($email,$subject){
            $message->to($email)->subject($subject);
        });
                ->with('title', "Registered Successfully.");

(I'm using SwiftMailer in PHP)

I was getting an error like that when I was accidentally sending a string for $email

$email = "[email protected] <Some One>";

When what I meant to be sending was

$email = Array("[email protected]"=>"Some One");

I was accidentally running it through a stringify function that I was using for logging, so once I started sending the array again, the error went away.

 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.

Data variables ($email, $subject) seems to be global. And globals cannot be read inside functions. You must pass them as parameters (the recommended way) or declare them as global.

Try this way:

Mail::send('emails.activation', $data, function($message, $email, $subject){
        $message->to($email)->subject($subject);
    });
            ->with('title', "Registered Successfully.");

Make sure your email address variable is not blank. Check using

print_r($variable_passed);
