I don't think I can really do that though, because the server is not the
smtp server, we are using a corporate server. If I remove that line, then
the code will "assume" the local box is the smtpserver. Anyway, I had
already tried that, but it doesn't make any difference either.

The box I'm trying this on is not directly on the domain on as the SMTP =
server, but it is trusted by that server. In addition, I had to request =
that box be added to the list of the SMTP server to be allowed to relay =
through it. I will look into this and see if it affects my situation.

Thanks,

i too faced a similar problem once.

it turned out that my mail server required that the sender be on the =
same domain as the smtp server.=20
eg: if my smtp server is "mail.abc.com"... then the sender has to be =
someone@abc.com.

just see if this applies to you as well.

Hello group:

I have reached the end of my rope with this error. I have pretty =
much tried every suggestion I've found thus far and I
get this error no matter what I do. I did try using the CDOSYS test =
from Microsoft as a test for the smtpserver, and it'll send that way.
Here's my existing code:

Public Sub SendMail()

Dim myMailMsg As New Mail.MailMessage()

With myMailMsg
.To =3D "<Send to address">
.From =3D <"Send From Address">
.Subject =3D "Test message"
.Body =3D "This is a test."
.BodyFormat =3D Mail.MailFormat.Text
End With
=20
Mail.SmtpMail.SmtpServer =3D "<smtp server>"
Mail.SmtpMail.Send(myMailMsg)

End Sub

For my SmtpServer, I've used localhost, smarthost, the actual value =
of our corporate smtp server address - nothing changes. I always get =
that
error message.

I have modifed the machine.config file, given the ASP.NET user =
process admin (temp) access, assigned the machine id of 127.0.0.1 to the =
Access tab for the relay settings, and every other suggestion I've found =
- nothing at all seems to make any change. I'm using Windows Server =
2003.

Can someone please help me? I don't know what else to do.

Thanks,

Hi James,

Firstly I want to thank all the people who provided help in this issue.

To isolate the root cause of this issue, I suggest that we test the
following console sample. Can you reproduce the same error?

HOWTO: Send E-mail Programmatically with System.Web.Mail and Visual Basic
..NET

If I have misunderstood your concern, please feel free to let me know.

Jacob,

Thanks again for your help. By using the example you gave via
Microsoft's knowledge site, I found (I think) what the problem was, although
the error message was confusing. I dropped in the code from the article
below, and it worked - absolutely no problem. But then I realized that the
code from that example was practically identical to mine.......except mainly
for one line.

In my declaration, I used:
Dim myMailMsg As New MailMessage()

In your example, the code used:
Dim oMsg As MailMessage = New MailMessage()

The difference was that I did not declare the variable type first, I was
just setting my variable equal to a new instance of the MailMessage Class
without declaring it "as" a MailMessage type variable.

What is strange, is that my original code worked on a Windows 2000 server,
but it did not on Windows 2003 Server, with both running the .NET Framework
version 1.1. The error would occur when the Send method was called on the
Mail.SmtpMail class.

I guess the error message was confusing because I normally am used to seeing
some sort of "object reference not set to an instance of an object" type
error.

Thoughts?

Hi James,

Thank you for your update. I am very glad to know that the original problem
is resolved.

As I understand, now you want to know why the error message is "The
transport failed to connect to the server". You think that it should be
something like "object reference not set to an instance of an object". Is
it correct?

If I have misunderstood your concern, please feel free to let me know.

Hi Jacob,

Yes, That is correct. It seems like I wasted alot of time trying to
troubleshoot a problem - my own fault, that is - at the expense of a
mis-leading error message.

Hi James,

Thank you for your update.

I have done a lot of research regarding this issue but I cannot reproduce
the error on my side.

That is to say, the following statement works on my side. (The "()" will be
removed by the VS.NET 2003 IDE automatically.)

Dim oMsg As New MailMessage

The following is my testing code. Please try it on your side.
----------------------------------------------------------------------------
-----------
Imports System.Web.Mail

Module Module1


Sub Main()

'Dim oMsg As MailMessage = New MailMessage

Dim oMsg As New MailMessage
' TODO: Replace with sender e-mail address.
oMsg.From = "jiany@microsoft.com"
' TODO: Replace with recipient e-mail address.
oMsg.To = "jiany@microsoft.com"
oMsg.Subject = "Send using Web Mail"

' SEND IN HTML FORMAT (comment this line to send plain text).
oMsg.BodyFormat = MailFormat.Html

'HTML Body (remove HTML tags for plain text).
oMsg.Body = "<HTML><BODY><B>Hello World!</B></BODY></HTML>"

' ADD AN ATTACHMENT.
' TODO: Replace with path to attachment.
' Dim sFile As String = "C:\temp\Hello.txt"
' Dim oAttch As MailAttachment = New MailAttachment(sFile,
MailEncoding.Base64)
'
' oMsg.Attachments.Add(oAttch)

' TODO: Replace with the name of your remote SMTP server.
SmtpMail.SmtpServer = "smarthost"
SmtpMail.Send(oMsg)

oMsg = Nothing
' oAttch = Nothing
End Sub

End Module

Hi,

I have been getting this error for some time now. What is getting
strange is that:
1. The same code works on our dev and prod servers but not on my
workstation;
2. The code sample from Microsoft's site works on my workstation.

What IS the real problem here?

Thanks a lot,

John
