通过hangfire发送邮件，不使用在webconfig

我和asp.net mvc 5、C#一起工作。我想通过hangfire发送邮件，而不需要从webconfing获取数据。在webconfig中，我有这个代码:

<mailSettings>
  <smtp from="email@site.com">
    <network host="host" port="25" userName="email@site.com" password="*****" enableSsl="false" defaultCredentials="false" />
  </smtp>
</mailSettings>

当我在Webconfig中使用时，一切正常工作。但是现在我想在数据库中存储电子邮件和密码，并从数据库中获取值。

这是。cs代码

 [AutomaticRetry(Attempts = 20)]
        public static void SendEmailToMember(Member obj,string Subject, string Details){        
        var viewsPath = Path.GetFullPath(HostingEnvironment.MapPath(@"~/Views/Emails"));
                var engines = new ViewEngineCollection();
                engines.Add(new FileSystemRazorViewEngine(viewsPath));
                var emailService = new Postal.EmailService(engines);
                var ee = new SendEmailToMember
                {
                    To = obj.Email,
                    FullName = obj.FullName,
                    Subject=Subject,
                    Details = Details,
                    ViewName = "SendEmailToMember"
                };
                emailService.Send(ee);
}

如何更改它以从数据库获取邮件设置?

        MailMessage mail = new MailMessage();
        SmtpClient smtpServer = new SmtpClient("smtp.gmail.com"); //gmail smtp server
        smtpServer.Credentials = new System.Net.NetworkCredential("loginFromDB", "passwordFromDB");
        smtpServer.DeliveryMethod = SmtpDeliveryMethod.Network;
        smtpServer..EnableSsl = false;
        smtpServer.Port = 587; // gmail works on this port
        mail.From = new MailAddress("yourMail@gmail.com");
        mail.To.Add("recepient@gmail.com");
        mail.Subject = "Hello from the other side";
        mail.Body = "your body";
        Postal.EmailService emailService = new Postal.EmailService(new ViewEngineCollection(), () => smtpServer);
        emailService.Send(email);
