Here is the code:

Dim objMailMessage As New MailMessage
objMailMessage.BodyFormat = MailFormat.Html
objMailMessage.From = "bl****@bla.ca"
objMailMessage.Subject = "Form Title"
objMailMessage.Body = strMessage

If Len(strEmailFrom) > 0 Then
strEmailTo += ";" & strEmailFrom
End If

objMailMessage.To = strEmailTo
SmtpMail.SmtpServer = "127.0.0.1"
SmtpMail.Send(objMailMessage)
This works on our testing server which uses a network service, but it
does not work on our production server which does not. Any ideas? I
know about the FAQ site System.WEb.Mail, OH MY!, and we have tried all
of their suggestions and none of them work.

Smtp.SendUsing = 2

When I enter in the code you suggested it cannot be compiled in Visual
Studio .NET 2003. it gives me the following error:

Name 'smtp' is not declared

I have imported System.Web.Mail only. Should I be importing something
else as well?

If you upgrade to 2005 you probably won't have this problem. Here's a
sample of sending email from .NET 2.0:

MailMessage msg = new MailMessage();
msg.From = new MailAddress("te**@test.com");
msg.To.Add("te**@test.com");
msg.Subject = "test subject";
msg.Body = "test body";

SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.yourdomain.com";
smtp.Send(msg);

But, if you want to continue using CDO.Message (which MailMessage in <
..NET 2.0 wraps) you need to set the SendUsing property to 2. I have no
idea how to set it from .NET but here's some sample C++ code to get you
started:

#import <msado15.dll> no_namespace rename("EOF", "adoEOF")
#import <cdosys.dll> rename_namespace("CDO") rename("EOF", "adoEOF")

....

CDO::IMessagePtr pMail = NULL;
pMail.CreateInstance(__uuidof(CDO::Message));

pMail->put_To("te**@test.com");
pMail->put_From("te**@test.com");
pMail->put_Subject("test subject");
pMail->put_TextBody("test body");

CDO::IConfigurationPtr pConfig(__uuidof(CDO::Configuration));
FieldsPtr pFields = pConfig->GetFields();
pFields->Item["http://schemas.microsoft.com/cdo/configuration/smtpserver"]->Value

=
_variant_t("smtp.yourdomain.com"); pFields->Item["http://schemas.microsoft.com/cdo/configuration/smtpserverport"]->Value
= _variant_t((long)25);
pFields->Item["http://schemas.microsoft.com/cdo/configuration/sendusing"]->Value
= _variant_t(2);
pFields->Update();

pMail->Configuration = pConfig;
pMail->Send();

The most important line is the one that sets the SendUsing property to
2.

Best of luck,

OK, here's some c# code that works for me.

MailMessage msg = new MailMessage();
msg.To = "te**@test.com";
msg.From = "te**@test.com";
msg.Subject = "test subject";
msg.Body = "test body";
msg.Fields["http://schemas.microsoft.com/cdo/configuration/smtpserverport"]
= 25;
msg.Fields["http://schemas.microsoft.com/cdo/configuration/smtpserver"]
= "smtp.yourdomain.com";
msg.Fields["http://schemas.microsoft.com/cdo/configuration/sendusing"]
= 2;
SmtpMail.SmtpServer = "smtp.yourdomain.com";
SmtpMail.Send(msg);

Translating it into VB should be as simple as changing the first line.
Sorry it tooks so long, I'm normally a c++ developer not a .NET
developer.

Best of luck,

Sure this won't matter, but I use:

SmtpMail.SmtpServer = "localhost"

Is your SMTP server configured and working on your production server?

Have you added 127.0.0.1 to the unresticted list for relaying? (AFAIR, I ran
into this problem when I switched from Win2K to WinXP for my development
machine). Not sure if the same thing applies for Win2003 Server or not....

IIS->Default SMTP->Properties->Access tab->Relay button.
