页面代码如下

<body>

<div>

<tr>

发件人:</td>

<asp:TextBox ID="tb_From" runat="server"></asp:TextBox>

</td>

<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ErrorMessage="发件人地址不正确!!!"

Style="z-index: 100; left: 0px; position: relative; top: 0px" ControlToValidate="tb_From" Display="Dynamic" ValidationExpression="w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*"></asp:RegularExpressionValidator></td>

</tr>

<tr>

收件人:</td>

<asp:TextBox ID="tb_To" runat="server" ></asp:TextBox>

</td>

<asp:RegularExpressionValidator ID="RegularExpressionValidator2" runat="server" ErrorMessage="收件人地址不正确!!!" ControlToValidate="tb_To" Display="Dynamic" ValidationExpression="w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*"

></asp:RegularExpressionValidator>

</td>

</tr>

<tr>

主题:</td>

<asp:TextBox ID="tb_Sub" runat="server"></asp:TextBox>

</td>

</tr>

<tr>

内容:</td>

<asp:TextBox ID="tb_body" runat="server" Height="148px"></asp:TextBox>

</td>

</tr>

<tr>

<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="发送" />

<asp:Label ID="lab_Statu" runat="server" Width="213px"></asp:Label>

</td>

</tr>

</table>

</div>

</form>

程序代码如下(c#):

protected void Button1_Click(object sender, EventArgs e)

{

string mailServerName = ConfigurationSettings.AppSettings["mailserver"];

string mailFrom = tb_From.Text ;

string mailTo = tb_To.Text;

string mailSub = tb_Sub.Text; ;

string mailBody = tb_body.Text;

try

{

using (MailMessage message =

new MailMessage(mailFrom, mailTo, mailSub, mailBody))

{

// SmtpClient is used to send the e-mail

SmtpClient mailClient = new SmtpClient(mailServerName, 25);

// UseDefaultCredentials tells the mail client to use the

// Windows credentials of the account (i.e. user account)

// being used to run the application

mailClient.UseDefaultCredentials = true;

// Send delivers the message to the mail server

mailClient.Send(message);

}

lab_Statu.Text = "send success!!!";

}

catch (SmtpException ex)

{

lab_Statu.Text = ex.Message;

}

catch (Exception ex)

{

lab_Statu.Text = ex.Message;

}

邮件服务器的地址是在web.config中配置的

</appSettings>

还有可能就是遇到"邮箱不可用。服务器响应为: 5.7.1 Unable to relay for "

解决的方法是:

在IIS中，右击“默认SMTP虚拟服务器”，选择“属性”，切换到“访问”页，点击“中继”按钮，在弹出框中选择“仅以下列表除外”，确定。

呵呵，这样应该就可以解决了～
