尝试从ASP.NET页面通过SMTP发送电子邮件时的权限问题
尝试从ASP.NET页面通过SMTP发送电子邮件时的权限问题
提问于 2011-05-04 20:48:21
我以前这样做过，没有任何问题，但现在我不知道哪里出了问题。我有一个网页的电子邮件按钮，我想发送一些数据到电子邮件地址。
我向我们的虚拟主机公司询问了服务器的详细信息，得到的答复是：
"You can use the following details for mail.
Incoming mail server: mail.ourSite.com Outgoing mail server: mail.ourSite.com
Username and password are the email address and password associated with the email address.
"我不确定最后一行，但我在web主机的控制面板中创建了一个新的电子邮件地址。
我使用的代码是：
// instantiate a new mail definition and load an html
// template into a string which I replace values in
// then the rest of the code below
md.Subject = String.Format("{0} {1} {2}", emailSubject, firstName, lastName);
MailMessage msg = md.CreateMailMessage(emailAddress, replacements, emailBody, new Control());
md.IsBodyHtml = true;
SmtpClient sc = new SmtpClient(emailServer);
sc.Credentials = new NetworkCredential(emailUsername, emailPassword);
try
{
sc.Send(msg);
}emailServer - mail.ourSite.com (本文中的虚拟值) emailUsername -我在控制面板中创建的电子邮件地址emailPassword -上面电子邮件的密码
我的错误是，当我向我们自己的域以外的其他域发送电子邮件时，我会收到
"Bad sequence of commands. The server response was: This mail server requires authentication when attempting to send to a non-local e-mail address. Please check your mail client settings or contact your administrator to verify that the domain or address is defined for this server."当我向我们主机内的地址发送电子邮件时，它工作得很好。
支持不是很支持，所以我在这里问你可能认为问题是什么？我发现我用我创建的电子邮件地址的密码很奇怪，真的应该这样吗？

我认为您使用了错误的NetworkCredential电子邮件地址。它应该是您从提供emailServer的电子邮件帐户中获得的电子邮件帐户。

试试这个..。
msg.UseDefaultCredentials = false;
NetworkCredential MyCredential = new NetworkCredential("Email", "Password");
msg.Credentials = MyCredential;Stack Overflow用户

下面是发送邮件的代码。我希望我能对你有所帮助。
using System.Web.Mail;
using System;
public class MailSender
{
public static bool SendEmail(
string pGmailEmail,
string pGmailPassword,
string pTo,
string pSubject,
string pBody,
System.Web.Mail.MailFormat pFormat,
string pAttachmentPath)
{
try
{
System.Web.Mail.MailMessage myMail = new System.Web.Mail.MailMessage();
myMail.Fields.Add
("http://schemas.microsoft.com/cdo/configuration/smtpserver",
"smtp.gmail.com");
myMail.Fields.Add
("http://schemas.microsoft.com/cdo/configuration/smtpserverport",
"465");
myMail.Fields.Add
("http://schemas.microsoft.com/cdo/configuration/sendusing",
