Vista - SMTPClient Authentication problems

I am having problems Authenticating to my SMTP Server. The code I am using is
as follows

public void SendMail(string fromAddress, string toAddress, string subject,
string body, string Password)
{
try
{
MailMessage msg = new MailMessage();
msg.From = new MailAddress(fromAddress);
msg.To.Add(new MailAddress(toAddress));
msg.Subject = subject;
msg.Body = body;
msg.IsBodyHtml = false;
SmtpClient smtp = new SmtpClient();
smtp.Host = "myemailserver.net";
smtp.Port = 25;

smtp.UseDefaultCredentials = false;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Credentials = new
System.Net.NetworkCredential("testaccount", "design");
smtp.EnableSsl = false;
smtp.Send(msg);
//return true;
}
catch (Exception ex)
{
///Log.Write(ex)
//return false;


}
}

when I view the log on the smtp server I get

[12-09 11:08:23] 98.172.47.252: SMTP_client: SMTP/CONNECT
[12-09 11:08:23] 98.172.47.252: SMTP_server: 220 netresolutions.com AAMail

I am far from an expert on SMTP but it appears that it is only sending over
the paasword and not the login information. but if I new that for sure I
woulnt be here asking. any help would be apprecitated

I am using VS2008, .net 2.0/3.5, silverlight 2
thanks

This should help you.

You can download the code and reuse the library ... OR you can at least
tweak until you figure out which parameters you need to set.

I would reuse the small library.

I lookat at the code it used I am using all the exact settings it is for the
message and smtp client settings for basic authentication.

Did you try to run my code and see if it failed?

I'm guessing, but maybe chronological order of the MailMessage and
SmtpClient makes a difference (<<I wouldn't think it would, but it
might....I've seen weird stuff)
?
Or maybe the constructor I'm using or MailMessage?

See if my example works, and then if it doesn't, then post the results.

Are you sure about the port?
........

I have my used my example in 6 different environments
(home/work/staging/production/hosted sites, etc), one of the reasons I trust
it.

What is great about my library, is that with a few tweaks of the config
file, you can experiment with NONE/BASIC/SSL.
Try the others ones.
Try to get my code up and running.

I'm not trying to be argumentative, I'm just trying to help you.

Then I don't know.

Did you wire up SSL just to make sure?

Is your Outlook setup for Exchange Server or SMTP?

..........

My only leftover advice is to delete (or create a new) profile in Outlook,
and work through (re setup) the smtp setup settings to make sure you're not
missing something.

I would redo the Outlook setup just to verify your username/password are
correct.

I don't think its a DotNet issue, I think its a simple issue like the wrong
port or wrong userName/password combination.

I am not using ssl and outlook works with the server why would I change the
username and pass?

I set up a sniffer earlier and the handshake between outlook is different
then the handshake with dotnet
