Strange sender of emali...

Hello there, here I am (again)...

I want to use SMTP in a project, and it work. 
BUT
I set the 

Code:

$email->setFrom('[email protected]', 'MySender');

and in the recieved mail is given following: SandBox CI4 ([email protected]),
but I want to get THIS: MySender ([email protected])

Where the hell is the "SandBox CI4" from ?!?

I searched the folder of my installation, but I got no results...

Where to set the correct sender of the email ?

but I want to get THIS: MySender ([email protected])

I checked, there is no problem.
Providing more code details can help solve your problem.

Here are all the settings I made related to the email class:

Controller:

PHP Code:

public function testEmail()
    {
        $email = service('email');
        $email->setFrom('[email protected]', 'St.Barbara Familienzentrum');
        $email->setTo('[email protected]');
        $email->setSubject("Eine Test-Email");
        $email->setMessage("<h1>Hallo Testnachricht</h1>");
        if ($email->send()) {
            echo "Nachricht gesendett...";
        } else {
            echo $email->printDebugger();
        }
    } 


.env file

PHP Code:

email.SMTPHost = 'myhost.provider.com'
email.SMTPUser = 'myUserName'
email.SMTPPass = 'xXxXxXxXxX'
email.SMTPPort = '587'
email.SMTPCrypto = 'tls' 


(With my correct credentials sending emails is working)

Nowhere I can see "SandBox CI4", but in my eMail Client this is the sender...

Check with printDebugger:
https://codeigniter4.github.io/CodeIgnit...ntDebugger

The values are CI's email values.

If you do not see the same sender name, this may be due to your SMTPHost or your email client.
