Sending Email with ASP.NET

stu9820 · October 29th, 2003, 12:10 PM

I tried that but it didn't work. What I ended up doing was finding the DNS of a valid SMTP server on the LAN here and used it instead of my test server.

Dear all:

I have try to send an email by IIS Smtp Server, by this code:
SmtpMail.SmtpServer = "10.97.3.129"

But i have a big problem here, the IP Address on my PC is just temporary as it will be changed everytime i connect to the Internet(i use the prepaid Intenet Service)

So, i have tried to chage the code to:
SmtpMail.SmtpServer = "localhost" or
SmtpMail.SmtpServer = "myComputerName"

Although the message show that the email adready send, but i can't receive the mail anymore!

Pls kindly help me to solve the problem as this is my final year project!

Thanx for your solution!

Regards...

Make sure your objMail.To = "" has a valid address in it. I use my own email when testing.

Hi Stu9820

I had trouble with the MailMessage at first, but here's some solutions:

                /* When sending mail be sure the moden is connected to the internet,
                 * and that the virus-checker is NOT checking outgoing mail.
                 * Then using "mailto:localhost" can be used but only seems to
                 * add another receipient. */
                MailMessage dealer_message = new MailMessage();
                dealer_message.To = "[email protected]";
                dealer_message.From = "[email protected]";
                dealer_message.Subject = "Testing Information";
                dealer_message.BodyFormat = MailFormat.Text;
                dealer_message.Body = "Request for Information from ";
                SmtpMail.SmtpServer = "mail.earthlink.net";
                SmtpMail.Send(dealer_message);

The SmtpServer address has to be the mail server of the location from which the e-mail is being sent.
My ISP is www.webhost4life.com, so I change it to the SmtpServer there:
SmtpMail.SmtpServer = "mail.webhost4life.com";
although the way they are set up that doesn't work as well as:
SmtpMail.SmtpServer = "xx.xxx.xxx.xxx"; // which is the IP of my site.

Dear all,

How I can make a link to outlook express by clicking on the EMAIL column in the datagrid???
Before that, I used the code as below:
<A HREF="mailto:<%# DataBinder.Eval(Container.DataItem, "EMAIL") %>">
<%# DataBinder.Eval(Container.DataItem, "EMAIL") %></A>

But right now, I retrieved the data from database into datagrid using code behide. So, how I can make the link?

Any Idea?

Cheers,

It is possible to authenticate with the .Net MailMessage object. It is done through the Fields property:

Sample C# code:

//Use the following fields to add authentication, if necessary
//0 = None / 1 = Basic / 2 = NTLM
myMailMessage.Fields["http://schemas.microsoft.com/cdo/configuration/smtpauthenticate"] = 1;
myMailMessage.Fields["http://schemas.microsoft.com/cdo/configuration/sendusername"] = "myusername";
myMailMessage.Fields["http://schemas.microsoft.com/cdo/configuration/sendpassword"] = "mypassword";

Hi All,
I am in a problem. The point is that I am trying to send mail from an ASP.Net webpage using the following code:

System.Web.Mail.MailMessage msg1 = new System.Web.Mail.MailMessage();
msg1.From = "[email protected]";
msg1.To = "[email protected]";
msg1.Subject = "Testing";
msg1.Body = "Hello";
System.Web.Mail.SmtpMail.SmtpServer = "localhost";
System.Web.Mail.SmtpMail.Send(msg1);

The smtp server on my local host is not configured to send emails. So I changed the "smart host" in advanced properties of IIS Local SMTP, I gave the server name of a machine which is on the LAN and is configured to send emails.

Now the error that I am getting is that:
The server rejected one or more recipient addresses. The server response was: 550 5.7.1

But the recipient address is absolutely right. There is nothing wrong in it. What should i do?

Hi all This is my first post. For sending the mail i m using following code:
Sub SendMail()
        Dim sr As New StreamReader(Server.MapPath("slammail.htm"))
        Dim msgBody As String = sr.ReadToEnd
        sr.Close()
        msgBody = msgBody.Replace("Account_Username", txtUserName.Text)
        msgBody = msgBody.Replace("Account_UserPassword", txtPassword.Text)
        msgBody = msgBody.Replace("Account_SlamUrl", txtUserName.Text)

        Dim smtpServer As String = "webmail.xxx.com"
        Dim userName As String = "[email protected]"
        Dim password As String = "xxx"
        Dim cdoBasic As Integer = 1
        Dim cdoSendUsingPort As Integer = 2
        Dim objMail As New System.Web.Mail.MailMessage

        objMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserver", smtpServer)
        objMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport", 25)
        objMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusing", cdoSendUsingPort)
        objMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", cdoBasic)
        objMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "[email protected]")
        objMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "xxx")
        'Dim objMail As New MailMessage
        objMail.To = txtEmail.Text
        objMail.From = """xxx""" & "xxx"""
        objMail.Subject = "Welcome to xxx"
        objMail.BodyFormat = MailFormat.Html
        objMail.Body = msgBody
        Try
            SmtpMail.SmtpServer = "localhost"
            SmtpMail.Send(objMail)
        Catch ex As Exception
            'SmtpMail.SmtpServer = "localhost"
            SmtpMail.Send(objMail)
        End Try
    End Sub

As this method required username password which is not always work when i work for my some client as they are not willing to give his password to me. Can somebody please tell some method of sending authenticate mail without the requirement of password.
