Question

我想在asp.net中使用PasswordRecovery控件恢复密码。但是当我点击提交按钮时。我收到了以下消息：

错误的命令序列。服务器响应是：此邮件服务器在尝试发送到非本地电子邮件地址时需要身份验证。请检查您的邮件客户端设置或联系您的管理员以验证是否为此服务器定义了域或地址。这是我的HTML代码：

<asp:PasswordRecovery ID="PasswordRecovery1" runat="server" 
          style="font-family: Tahoma; font-size: small" 
          onsendingmail="PasswordRecovery1_SendingMail" >
          <MailDefinition BodyFileName="../User Pages/RecoveryPass.htm" From="info@shirinfam.com"
            IsBodyHtml="True" Subject="بازیابی کلمه ی عبور" Priority="High"></MailDefinition>
        <UserNameTemplate>
            <table cellpadding="1" cellspacing="0" style="border-collapse:collapse;">
                <tr>
                    <td>
                        <table cellpadding="0">
                            <tr>
                                <td align="center" colspan="2">
                                    &nbsp;</td>
                            </tr>
                            <tr>
                                <td align="center" colspan="2">
                                    <asp:Label ID="Label1" runat="server" 
                                        Text="<%$ Resources:resource, passrecovery %>" 
                                        style="font-size: small; font-family: Tahoma"></asp:Label></td>
                            </tr>
                            <tr>
                                <td align="right">
                                    <asp:Label ID="UserNameLabel" runat="server" AssociatedControlID="UserName"></asp:Label>
                                </td>
                                <td>
                                    <asp:TextBox ID="UserName" runat="server"></asp:TextBox>
                                    <asp:RequiredFieldValidator ID="UserNameRequired" runat="server" 
                                        ControlToValidate="UserName" ErrorMessage="User Name is required." 
                                        ToolTip="User Name is required." ValidationGroup="PasswordRecovery1">*</asp:RequiredFieldValidator>
                                </td>
                            </tr>
                            <tr>
                                <td align="center" colspan="2" style="color:Red;">
                                    <asp:Literal ID="FailureText" runat="server" EnableViewState="False"></asp:Literal>
                                </td>
                            </tr>
                            <tr>
                                <td align="right" colspan="2">
                                    <asp:Button ID="SubmitButton" runat="server" CommandName="Submit" Text="<%$ Resources:resource, submit %>" 
                                        ValidationGroup="PasswordRecovery1" Font-Names="tahoma" 
                                        Font-Size="X-Small" Width="80px" />
                                </td>
                            </tr>
                        </table>
                    </td>
                </tr>
            </table>
        </UserNameTemplate>
</asp:PasswordRecovery>

这是背后的代码：

protected void PasswordRecovery1_SendingMail(object sender, MailMessageEventArgs e)
    {
        SmtpClient smtp = new SmtpClient();

        smtp.Send(e.Message);
    }

这是web.config中的smtp设置：

 <system.net>
    <mailSettings >
      <smtp >
        <network host="mail.domainname.com" userName="info@dominname.com" password ="password" defaultCredentials="false"/>
      </smtp>
          </mailSettings>
  </system.net>

Answer 1

为您的电子邮件帐户设置credentials，假设您使用的是Gmail帐户发送电子邮件，那么您必须将credentials (username and password)设置为smtpClient object }。

以下是示例::

 MailMessage m = new MailMessage();
 SmtpClient sc = new SmtpClient();

MailMessage帮助我们创建邮件，SmtpClient允许我们向收件人发送邮件。

注意：以下代码配置为从GMAIL帐户发送邮件..

m.From = new MailAddress("from@gmail.com", "Display name");
m.To.Add(new MailAddress("to@domain.com", "Display name To"));
m.Subject = "Test";
m.Body = "This is a Test Mail";
sc.Host = "smtp.gmail.com";
sc.Port = 587;
sc.Credentials = new System.Net.NetworkCredential("from@gmail.com", "password of from");
sc.EnableSsl = true; // runtime encrypt the SMTP communications using SSL
sc.Send(m);

Answer 2

DefaultCredentials应设置为true，并应明确将凭据添加到客户端。

SmtpClient client = new SmtpClient(server, port);
        // Credentials are necessary if the server requires the client 
        // to authenticate before it will send e-mail on the client's behalf.
        client.Credentials = CredentialCache.DefaultNetworkCredentials;
