当邮件服务器在本地网络中时，如何在没有凭据的情况下在 .Net Core 中添加 SMTP

Question

如何在没有凭据的情况下在 .NET Core 2.1 中设置我的 SMTP 客户端。我的邮件服务器在网络内。

private async Task<bool> SendEmailToCustomer(string customerEmail, string Message)
{
    try
    {
        SmtpClient client = new SmtpClient(SmtpConfig.server);

        if (SmtpConfig.userName != "" && SmtpConfig.password != "")
        {
            client.UseDefaultCredentials = false;
            client.Credentials = new NetworkCredential(SmtpConfig.userName, SmtpConfig.password);
        }

        //client.DeliveryMethod = SmtpDeliveryMethod.Network;
        MailMessage mailMessage = new MailMessage();
        mailMessage.From = new MailAddress(SmtpConfig.fromForCustomer);
        mailMessage.To.Add(customerEmail);
        mailMessage.Body = Message;
        mailMessage.Subject = SmtpConfig.subjectForCustomer;
        await client.SendMailAsync(mailMessage);
        return true;
    }
    catch (Exception ex)
    {
        return false;
    }
}
