mg.Body = "sdafadsf";

mg.From = "[e-mail]";//"[e-mail]";
mg.FromName = "[e-mail]"; // "email";
mg.Html = false;
mg.MailDomainPort = 25;

mg.MailServerPassWord = "010000";// "email";
mg.MailServerUserName = "dys_198102";// "email";
mg.Subject ="你好";


mg.AddRecipient("[e-mail]");
mg.RecipientName ="390238244";
mg.MailDomain = "yahoo.com.cn";// "60.190.222.222";
mg.Send();
Response.Write("<script language='javascript'>alert('ok');</script>");
}
能正常运行,但收不到邮件

大家帮忙看看是哪里的问题？？谢谢

现在很多邮箱都不支持SMTP发信了

163的那个邮箱是啥时候申请的，要是2007年之前的还可以发信，2007年后申请的新用户都不可以发信了

页面生存时间的问题，ajax调用可以看作是一个static的方法或者是一个webservice,在你请求发过去的时候，页面类 test 的实例已经不存在了，怎么调用的到？

[lovehongyun]

换个邮箱试试.

我用System.Net.Mail.SmtpClient发邮件都可以正常发送.

[dys_198102]

现在可以发送邮件了．就是那个从数据库中提取数据传值那．有问题．．．．

[sh_suyuelin]

这个问题不久前我遇到过。。邮件问题。换邮箱

[dys_198102]

楼上的兄弟肯定没有最后发的几条，现在的问题是页面加载时打开数据库把值付给公共变量．当提交时运用ＡＪＡＸＰＲＯ发邮件．提交时公共变量没有值为空，也就是说值没有传过来．
[AjaxPro.AjaxMethod]
public string sendemails(string title,string email,string body)
{
MailMessage mailMessage = new MailMessage();
string strBody;

//发送地址
mailMessage.From = new MailAddress(sendemail);

//接收地址
mailMessage.To.Add(j_email);

//邮件标题
mailMessage.Subject = "测试";

mailMessage.BodyEncoding = System.Text.Encoding.UTF8;

//邮件内容
strBody = "测试哈哈！！傻样．．．．";
mailMessage.Body = strBody.Trim();

SmtpClient smtpClient = new SmtpClient();
//smtpClient.EnableSsl = true; //Smtp服务器

不用ＡＪＡＸ就可以传值了，不过有一个用Ｃ＃验证ＥＭＡＩＬ的程序，
public static bool IsEmail(string str_Email)
{
return System.Text.RegularExpressions.Regex.IsMatch(str_Email, @"\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*");
} 这是在网站看别人的．

protected void Button1_Click1(object sender, EventArgs e)
{
string tt = TextBox2.Text.ToString().Trim();
if (this.TextBox1.Text.ToString() == "" || this.TextBox2.Text.ToString() == "" || this.TextBox3.Text.ToString() == "")
{
this.Label2.Text = "The title of your mailbox, mail content can not be empty!";
}
[color=#FF0000] else if (IsEmail(tt))
{
this.Label2.Text = "You have entered an incorrect e-mail format!";
}如果随便输入字符，这部分没运行，应报错才对．这里怎么用IsEmail()[/color]
else
{
