SMTP Email VB.net 2008

[Brian]

Hello all, we don't actually host our own server but still should work
the same.

Here is the error message i get
"error mailbox unavailable. The server response was: must be
authenticated code 550"

and below is the code. the only thing i had to to do was change the
port as our isp blocks 25. Just wondering if anyone has run into this
beefore. TIA

' this calls the sendsimple mail
Private Sub Button1_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button1.Click
SendSimpleMail( "Us******@domai n.com", "Us******@domai n.com",
"Yikes", "This is a test")
End Sub
Public Sub SendSimpleMail( ByVal FromAddr As String, ByVal ToAddr As
string, _
ByVal Subject As String, ByVal Body As String)
'

Dim Client As SmtpClient

Dim Message As MailMessage

' SMTP server goes here
Client = New SmtpClient("SMT P.domain.com")
Client.Credenti als = New
System.Net.Netw orkCredential(" username??", "Password")
'Portproperties
Client.Port = 587

' Simple plain text message
Message = New MailMessage(Fro mAddr, ToAddr, Subject, Body)

' Send message
Try
Client.Send(Mes sage)
Catch ex As SmtpException
MsgBox("Error: " & ex.Message & " Code: " & ex.StatusCode, _
MsgBoxStyle.Exc lamation Or MsgBoxStyle.OkO nly, "SMTP Error")
End Try

Message = Nothing
Client = Nothing

End Sub

If you selected the right port using proper credentials, but still no
luck at sending mail, you should also check if your SMTP server
requires SSL to be enabled, so add this:

' EnableSsl is a member of SMTPClient
client.EnableSs l = True

..hope it helps,

Not sure, first you should check your mailbox's health by accessing
using any mail program like Outlook Express if it's really running,

Secondly, make sure you're entering correct username and password,

Sorry if it doesn't help,

I actually have been running this mail account through thunderbird for
about a year now without any problems that is why i am at a loss.

our host is 1and1.com but we have our own domain xyz.com
and when I login it's us******@xyz.co m but of course the Imap and smtp
our both 1and1.com
