Default 5.7.1 Authentication Required

In chapter 9, page 319 and 323, I keep getting the error "5.7.1 Authentication Required" using verizon.net mail services. I hate sending this message because I think I need information from verizon. My problem is I'm getting answers like "Can't you add authentication in your code?" Can someone help me solve this problem or give me a succinct question I can ask so that verizon will understand what I need?

I'm using port 25 because the last verizon tech suggested it.

            <smtp deliveryMethod="Network" from="Dan McCrady &lt;danmccrady@verizon.net&gt;">
     <network host="outgoing.verizon.net" userName="danmccrady" password="XXXXXXX"
              port="25" />

Imports System.Net.Mail

    Protected Sub Send_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Send.Click
        If Page.IsValid Then
            Dim fileName As String = Server.MapPath("~/App_Data/ContactForm.txt")
            Dim mailBody As String = File.ReadAllText(fileName)

            mailBody = mailBody.Replace("##Name##", Name.Text)
            mailBody = mailBody.Replace("##Email##", EmailAddress.Text)
            mailBody = mailBody.Replace("##Phone##", PhoneNumber.Text)
            mailBody = mailBody.Replace("##Comments##", Comments.Text)

            Dim myMessage As MailMessage = New MailMessage()
            myMessage.Subject = "Response from web site"
            myMessage.Body = mailBody

            myMessage.From = New MailAddress("DanMcCrady@verizon.net", "Dan McCrady")
            myMessage.To.Add(New MailAddress("DanMcCrady@verizon.net", "Dan McCrady"))

            Dim mySmtpClient As SmtpClient = New SmtpClient()

            Message.Visible = True
            FormTable.Visible = False

        End If
    End Sub

Hi there,

Looks like you're doing the right things already. Setting the user name and password is the way to go. Two things I can think of why this doesn't work:

1. Your user name may not be complete and should be something like danmccrady@verizon.net or another domain.

2. They require you to use SSL in which case you can set the enbleSsl attribute and change the port number (typically 587, but Verizon may use a different port).

I had already tried enabling SSL and that clearly wasn't going to get past this problem.

I called Verizon's "advanced tech support" and they said it cannot be the username or password and this was out of their scope - issue closed. I took another try at it by changing the password and it now works. Thanks for the idea - maybe Verizon should send you a check!
