Question

电子邮件发送功能在托管应用程序中无效。但它正在本地机器上工作。代码是

[WebMethod]
    public static string SendMail(string To,string Subj,string Body)
    {

        MailMessage emailmsg = new MailMessage();
        emailmsg.From = new MailAddress("salam@rainhopes.com");
        emailmsg.To.Add(To);
        emailmsg.Subject = Subj;
        emailmsg.Body = Body;
        emailmsg.IsBodyHtml = true;

        //SMTP SERVER DETAILS
        SmtpClient smtpc = new SmtpClient("smtp.gmail.com");
        smtpc.Port = 587;
        smtpc.UseDefaultCredentials = false;
        smtpc.EnableSsl = true;
        smtpc.Credentials = new NetworkCredential("salam@rainhopes.com", "******");
        smtpc.Send(emailmsg);
        return " your email send sucessfuly!.. check your email";
    }

Answer 1

在<system.web>下的web.config中添加<customerrors mode="Off">以查看完整异常

 <system.web>
    <customErrors mode="Off"/>
    <compilation debug="true"/>
    <authentication mode="None"/>
  </system.web>
  </configuration>

Answer 2

检查您的SMTP配置，gmail是：

 <system.net>
    <mailSettings>
      <smtp>
       <network host="smtp.gmail.com" port="587" userName="eran@thereturnvalue.com" password="111111" defaultCredentials="false" />
      </smtp>
    </mailSettings>
  </system.net>
