Sending email through asp.net web app

Hi,
I am working on an intranet web application and need to be able to send
email through the application. I have to use an Exchange server to do this.
Can you tell me what I need to set up, what information I need to have or
collect?

Thanks.

Hi,

First of all speak with the network administrator and ask for an SMTP
server to rely on and send e-mails, problably he will give you an address,
user and password, check with a telnet if it's working fine:

Once you have checked that the account is working fine, you can code the
..net code, use system.net.mail namespace:

http://www.systemnetmail.com/

More info about how to send e-mails on .net:

Good luck

Thanks for the reply Braulio. I conatcted the administrator and was
given the mail server name. I was told I do not require user id and
password. So, in my web.config I added:

and in the aspx file:

protected void Button1_Click(object sender, EventArgs e)
{
string strFrom = "me@here.com";
string strTo = "you@here.com";
MailMessage mm = new MailMessage(strFrom, strTo);
mm.Subject = "Test Email from ASP.NET";
mm.Body = "This is a test email sent from within an ASP
application.";
mm.IsBodyHtml = false;
mm.Priority = MailPriority.Normal;
SmtpClint sc = new SmtpClient();
// SmtpClient sc = new SmtpClient("mailrelay.agencyname.gov");
// sc.Credentials = new NetworkCredential();
sc.Send(mm);
}

I get an error from Symantec Email Proxy:

Your email message to you@here.com
with mail subject of
Test Email from ASP.NET
was unable to be sent because the connection to your mail server was
interrupted.
Please open your email client and re-send the message from the Send
Message folder.

I tried changing the web.config to read:

but got the same error.

Thanks.

OK, I got it.
I was testing this from my workstation and I already had setup an SMTP
server (from within Outlook) and when I tried to use the other SMTP
server (mailrealy...., given to me by administrator) from within the
application, it choked. If I use the same SMTP server as listed in
Outlook, it works fine. Thank you all for your suggestions and help.
