Question

如果满足某些条件，我正试图从我的asp.net网页发送电子邮件。

这是我的代码。

SmtpClient smtpClient = new SmtpClient();
NetworkCredential basicCredential = 
    new NetworkCredential("username", "password"); 
MailMessage message = new MailMessage(); 
MailAddress fromAddress = new MailAddress("from@yourdomain.com"); 

smtpClient.Host = "mail.mydomain.com";
smtpClient.UseDefaultCredentials = false;
smtpClient.Credentials = basicCredential;

message.From = fromAddress;
message.Subject = "your subject";
//Set IsBodyHtml to true means you can send HTML email.
message.IsBodyHtml = true;
message.Body = "<h1>your message body</h1>";
message.To.Add("to@anydomain.com"); 

try
{
    smtpClient.Send(message);
}
catch(Exception ex)
{
    //Error, could not send the message
    Response.Write(ex.Message);
}

我没有分享服务器详细信息。我正试图从我的Outlook电子邮件地址发送它。但是，我一直收到错误： 发送邮件失败 。

Answer 1

试试这段代码

SmtpClient smtpClient = new SmtpClient("smtp.gmail.com", 25);

    smtpClient.Credentials = new System.Net.NetworkCredential("youremailid@gmail.com", "yourPassword");
    smtpClient.UseDefaultCredentials = true;
    smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
    smtpClient.EnableSsl = true;
    MailMessage mail = new MailMessage();


    //Setting From , To and CC
    mail.From = new MailAddress("fromemailid@gmail.com", "MyWeb Site");
    mail.To.Add(new MailAddress("toemailid@gmail.com"));
    mail.CC.Add(new MailAddress("ccemailid@gmail.com"));
    mail.Subject = "your subject";
    mail.IsBodyHtml = true;
    mail.Body = "<h1>your message body</h1>";

    smtpClient.Send(mail);

感谢，

Answer 2

要发送邮件，您无法使用开发服务器端口。

您必须使用邮件服务器的smtp服务器端口。

对于smtp.live.com，您应该使用端口25 or 587

对于以下代码，请指定VALID登录详细信息(email/password)

client.Credentials = new System.Net.NetworkCredential(
            @"email_account",
            @"email_password");

SMTP身份验证错误“发送邮件失败”
