PHPMailer 250 Verification

$mail->SMTPDebug = 2; will display all the things happened while we send mail.

It also displays SERVER -> CLIENT: 250 2.0.0 Ok: queued, which means all the checks were true (no issues in host/pot, etc) and mail has been sent.

Can we validate this in if condition?

Like

if("SERVER -> CLIENT: 250 2.0.0 Ok: queued" == "SERVER -> CLIENT: 250 2.0.0 Ok: queued"){
echo "sent";
} else {
echo "error"; }

Because below code will always show sent if the host is also not correct. (tested, then I came here).

try {
        $mail->IsSMTP(); 
        $mail->SMTPDebug  = 0;                     
        $mail->SMTPAuth   = true;                  
        $mail->Host       = "smtp.wrong.domain";      
        $mail->Port       = 587;               
        $mail->AddAddress("*****");
        $mail->Username="*****";  
        $mail->Password="*****";              
        $mail->SetFrom('*****','*****');
        $mail->AddReplyTo("*****@*****.*****","*****");
        $mail->Subject    = "*****";
        $mail->MsgHTML("Hi 587");
        $mail->Send();
echo 'Message has been sent';
} catch (Exception $e) {
    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
