Question

我在Godaddy上托管了一个ASP.NET应用程序，我希望从中发送电子邮件。当它运行时，我得到：不允许使用邮箱名称。服务器响应是：抱歉，从您的位置拒绝转发。代码的重要部分和Web.config如下：

msg = new MailMessage("accounts@greektools.net", email);
        msg.Subject = "GreekTools Registration";
        msg.Body =
            "You have been invited by your organization to register for the GreekTools recruitment application.<br/><br/>" +
            url + "<br/><br/>" +
            "Sincerely,<br/>" +
            "The GreekTools Team";

        msg.IsBodyHtml = true;

        client = new SmtpClient();
        client.Host = "relay-hosting.secureserver.net";

        client.Send(msg);

<system.net>
<mailSettings>
  <smtp from="accounts@greektools.net">
    <network host="relay-hosting.secureserver.net" port="25" userName="********" password="*********" />
  </smtp>
</mailSettings>

Answer 1

1-如果您的网站托管在godaddy上，您可以在没有凭据的情况下使用“relay-hosting.secureserver.net”。

2-如果您的网站是在godaddy之外托管的，您可以使用“smtpout.secureserver.net”与您的电子邮件帐户凭据。

PS：如果您遇到25

的问题，请更改3535端口

Answer 2

这是我的电子邮件课程：

public class Email
{
    public enum MailAddressType
    {
        From = 1,
        Bcc
    }

    private static MailAddress _from = null;

    public static void SendEmail(string to, string subject, string body)
    {
        SendEmail(to, subject, body, From, string.Empty);
    }

    public static void SendEmail(string to, string subject, string body, string from)
    {
        SendEmail(to, subject, body, from, MailAddressType.From);
    }

    public static void SendEmail(string to, string subject, string body, string addresses, MailAddressType addressType)
    {
        MailAddress from = From;
        string bcc = string.Empty;

        if (MailAddressType.From == addressType)
        {
            from = new MailAddress(addresses);
        }
        else
        {
            bcc = addresses;
        }

        SendEmail(to, subject, body, from, bcc);
    }

    private static void SendEmail(string to, string subject, string body, MailAddress from, string bcc)
    {
        MailMessage message = new MailMessage();
        message.From = From;
        message.To.Add(to);
        if (!string.IsNullOrEmpty(bcc))
        {
            message.Bcc.Add(bcc);
        }
        message.ReplyTo = from;
        message.Subject = subject;
        message.Body = HttpContext.Current.Server.HtmlEncode(body);
        SmtpClient smtp = new SmtpClient();
        smtp.Send(message);
    }

    public static MailAddress From
    {
        get
        {
            if (null == _from)
            {
                SmtpSection section = (SmtpSection)ConfigurationManager.GetSection("system.net/mailSettings/smtp");
                string address = section.From;
                string displayName = ConfigurationManager.AppSettings["fromEmailDisplayName"];
                _from = new MailAddress(address, displayName);
            }
            return _from;
        }
    }
}

以下是相关的web.config设置：

<appSettings>
    <add key="fromEmailDisplayName" value="Firstname Lastname"/>
</appSettings>

<system.net>
    <mailSettings>
        <smtp deliveryMethod="Network" from="myname@mydomain.com">
            <network host="relay-hosting.secureserver.net" />
        </smtp>
    </mailSettings>
</system.net>

对我来说，关键是“message.From = From”和“message.ReplyTo = from”。 GoDaddy似乎希望邮件来自您域中的地址。因此，对于联系人页面，请使用您的默认电子邮件地址作为发件人，并将发件人设置为ReplyTo。之后电子邮件会很好。

Answer 3

这可能是来自SMTP服务器的回复，因为尝试发送电子邮件的计算机尚未列入白名单（或已列入垃圾邮件列入垃圾邮件）。 relay-hosting.secureserver.net是GoDaddy服务器，还是在不同的网络上？您可能想要找到一个允许中继电子邮件的GoDaddy服务器。我想今天很多共享托管服务提供商都有限制。

我会找出您正在使用的SMTP服务器类型以及适当的反垃圾邮件措施。管理员可以将GoDaddy服务器添加到允许的主机的白名单中。您需要非常小心，并确保您的应用程序不能用作垃圾邮件发送者的代理。确保验证所有输入以确保其安全。

Answer 4

检查您的主机名。您确定您的帐户未配置为使用mail.greektools.net吗？这是GoDaddy虚拟主机的默认格式..

Answer 5

设置

defaultCredentials="false"

在你的网络元素

中

     <network host="relay-hosting.secureserver.net" port="25" userName="********" password="*********" defaultCredentials="false" />

Answer 6

只是为了测试。从web.config中删除用户名和密码值。

然后，在您的代码集中

//call this line, before you call .Send
client.Credentials = CredentialCache.DefaultNetworkCredentials; 
client.Send(msg)

Answer 7

我刚刚问GoDaddy，如何设置SMTP表单邮件，他们告诉我，我需要使用中继服务器，没有用户名，没有密码，也没有端口。要使用的服务器名称与您使用的名称相同。

Answer 8

What email or relay server should I use in my ASP.NET 3.5 code?

您无需提供用户名和中继服务器的密码。

Answer 9

var message = new MailMessage();
message.To.Add(new MailAddress("email-address")); 
message.From = new MailAddress("email-address");  
message.Subject = "subject";
message.Body = string.Format("message-body");
message.IsBodyHtml = true;
using (var smtp = new SmtpClient())
{
    smtp.Host = "relay-hosting.secureserver.net";
    smtp.EnableSsl = false;
    smtp.Credentials = CredentialCache.DefaultNetworkCredentials;
    await smtp.SendMailAsync(message);
}

Answer 10

对于那些想知道除了接受的答案之外应该知道C＃代码的人，下面的代码对我有用。请注意＆＃34;来自＆＃34;在接受的答案中已经在web.config中提到了地址，因此无需在C＃代码中提及它。

    public static void SendMail(string emailid, string subject, string body)
    {
        System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient();

        System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage();

        msg.To.Add(new MailAddress(emailid));

        msg.Subject = subject;
        msg.IsBodyHtml = true;
        msg.Body = body;

        client.Send(msg);
    }

Answer 11

尝试以下代码：

smtp.Host = "relay-hosting.secureserver.net";
smtp.Port = 25;
smtp.Credentials = new System.Net.NetworkCredential("test@yourwebsitedomain.com", "*******");

对我有用。

Answer 12

从C＃代码发送Go Daddy电子邮件的代码对我有用

var smtp = new SmtpClient
{
  Host = "smtpout.secureserver.net",
  Port = 25,
  UseDefaultCredentials = false,
  Credentials = new NetworkCredential("domain.xyz.com", "password...")
};
using (var message = new MailMessage("domain.xyz.com", "domain.xyz.com")
 {
    IsBodyHtml = false,
    Subject = modal.Subject,
    Body = modal.Body
 })
  {
   smtp.Send(message);
  }

无法通过Godaddy服务器在ASP.NET中发送电子邮件
