请问为什么我用SmtpMail和MailMessage不能发邮件.

honjo 2004-05-04 08:42:35

代码如下:
MailMessage msgMail = new MailMessage();
msgMail.To = honjo@sina.com; //邮件接受者
msgMail.From = "hong102@21cn.com";
msgMail.Subject = "您的定单信息。";

msgMail.BodyFormat = MailFormat.Html;
string strBody = "<html><body>Test mail messages!!!</body></html>"
msgMail.Body = strBody;
SmtpMail.SmtpServer = "localhost";
SmtpMail.Send(msgMail);

没有错误产生,但honjo@sina.com就是收不到邮件,
我用的是window2000server的IIS自带的smtp,服务已启,但会在\Inetpub\mailroot\Queue\下有邮件的文件,但就是不会向目标邮件发出去
妈的,搞了一天了,没搞出来,还望哪位有经验的赐教啊.

同意楼上的你要用base64写个验证过程要不你的邮件是发不出

原因事smtp服务器需要身分验证,发送邮件之前添加如下代码:
email.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1");
email.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername","用户帐号");
email.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword","用户密码");

代吗（包括邮箱的设置 stmp 的设置）没有错误的话你就现卸载组件再重新安装或者换台机子试试！

好像跟你的outlook配置也有关系，主要是邮件发送格式，sql server中发送邮件时，一般要求我把outlook的邮件发送格式设置为“纯文本”，所以我想这个问题是不是也这样

支持的.但要有权限.
就是邮件服务器(exchange等,或比如163的smtp服务器)要对你的服务器进行授权.准许你通过smtp

。net里面带的好像不支持Smtp服务器要求身份认证的情况，换OutLook的组件发送就能有这个功能。

可能是瑞星的问题，关闭邮件发送监控就好了，这个问题曾经困扰了我好久

搂住可以先用别的smtpserver试试，看看是不是你的smtpserver本身的问题

楼上这位大哥,我改了也不行,文件还是在\Inetpub\mailroot\Queue\这个文件夹里,
没有发出去,真是气死人了,
请问,是不是用这个东东发mail要设置其它什么地方呢,
我看了很多其它人的示例,好像都是这样的,为什么唯独我的就不行呢?
郁闷啊...郁闷啊...郁闷啊...郁闷啊...

SMTP的属性你设置了吗？
作为本地邮件服务器发送邮件你需要设置一些属性

首先，右击"默认SMTP虚拟服务器"
接着设置属性如下：　　
　　“访问”选项卡中设置访问权限。单击“身份验证”，选择“匿名访问”，表示任何用户都可以发送，其他两项不用选择；单击“连接控制”中的“连接”和“中段限制”中的“中断”，选中“仅以下列表除外”，表示可以许接入所有用户的访问。

　　“邮件”选项卡中设置邮件传输条件及限制，“限制邮件大小为”等四个选项可以使用默认值，无须更改；

　　“将未传递报告的副本发送到”可将发送不成功的邮件返回发件人，并且写明不成功的原因；“死信目录”设置没有发送成功的邮件被存放的位置。

　　“传输”选项中设置邮件传递时间，这里不用修改，使用默认值；“LDAP路由”选项用来指定服务器使用的目录服务器标识和属性，这里也不用启动它。

　　“安全”选项中设置使用发送服务器的有权用户，默认用户是“Administrators”，你可以单击“添加”添加使用用户。

用C#.Net编写的基于SMTP协议的邮件发送客户端. 包括邮件发送,联系人管理

演示在ASP。NET上发送邮件。演示Systm.web.mail命名空间类的用法。

Asp.net自动发送邮件 System.Web.Mail和System.Net.Mail下的发送邮件

基于 System.Web.Mail的邮件发送和接收类

程序中用到名称空间—System.Web.Mail类库里所提供的邮件发送的对象、属性和方法。可以将邮件发送到smtp邮件服务器上。
