Question

我创建了联系表格。我只需要从表单中获取用户数据并将其发送到我自己的电子邮件地址即可。我将我的Outlook登录名放在了vb代码中，但是我仍然收到发送电子邮件错误的失败消息。

我已经仔细检查了我的Outlook凭据，并且我也尝试了使用gmail帐户的脚本。我的脚本不好吗？还是这是防火墙问题？

Imports System.Net.Mail

Public Class WebForm1
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Try
            Dim Smtp_Server As New SmtpClient
            Dim e_mail As New MailMessage()
            Smtp_Server.Host = "smtp.outlook.com"
            Smtp_Server.Port = 587
            Smtp_Server.Credentials = New Net.NetworkCredential("myemail@outlook.com, "mypassword")
            Smtp_Server.EnableSsl = True
            Smtp_Server.UseDefaultCredentials = False
            Smtp_Server.DeliveryMethod = SmtpDeliveryMethod.Network


            e_mail = New MailMessage()
            e_mail.From = New MailAddress(txtFrom.Text)
            e_mail.To.Add("myemail@outlook.com")
            e_mail.Subject = "Email Sending"
            e_mail.IsBodyHtml = False
            e_mail.Body = txtMessage.Text
            Smtp_Server.Send(e_mail)
            MsgBox("Mail Sent")

        Catch error_t As Exception
            MsgBox(error_t.ToString)
        End Try

    End Sub

End Class

无论使用Outlook还是gmail，我都会收到以下错误消息。我的代码看起来不错，我不明白为什么不这样做。

联系表单错误：发送电子邮件失败。我只需要知道我的脚本是否不好，我就不这么认为
