Hello! I have some problem with smtp
when I try to use a variable as the mail receiver of the email, it doesn’t work. But if I write the mail receiver in the code myself - it works

This is my code:

        MailMessage mail = new MailMessage();
        SmtpClient SmtpServer = new SmtpClient("smtp.mail.ru");
        SmtpServer.Timeout = 100;
        SmtpServer.DeliveryMethod = SmtpDeliveryMethod.Network;
        SmtpServer.UseDefaultCredentials = false;
        SmtpServer.Port = 587;

        mail.To.Add(new MailAddress(mailReceiver));
        

        mail.Subject = "New feedback!";
        mail.Body = $"Thanks for your feedback!";
        

        SmtpServer.Credentials = new System.Net.NetworkCredential("hided mail", "hided password") as ICredentialsByHost; SmtpServer.EnableSsl = true;
        ServicePointManager.ServerCertificateValidationCallback = delegate (object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
        {
            return true;
        };

        mail.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
        SmtpServer.Send(mail);
