This is an article discussion thread for discussing the SitePoint article, "Sending Web eMail in ASP.NET"

great article that covers the basics. Quick question - what are the advantages of using the codebehind page rather than using script blocks?

zakruvalcaba · Nov 8, 2004, 16:37

Using script blocks, otherwise known as code declaration blocks requires interpretation similar to classic ASP. Code-behind allows for compilation which, in larger-scale apps could boost performance.

The RTFM people are coming, I can hear them, but to keep the explanation concise, there you go.

A very good article for quick revision .
But I want to know the properties used to pass the sender name also because all mail services show

from : "satya"<satya_chhikara@centrum.cz>
here my name is also passed to reciver . How this can be possible without passing . I want to know the property of mail class that passes sender name also like message.to , message.from

Please mail me at satya_chhikara@centrum.cz

Very Handy coding...really useful if one decided to implement.
Thanks
Bye.

even though pretty simple its just one of those improvements ( there are many more) that makes your life easier with asp.net compared to long forgotten asp

Hey guys

I know how to send web emails. But now i want to send an email through a server that requires authentication. How do i send the username and password to the server in the code.

Also i want the email to be from : Name Surname and wen u hit reply it replies to the right email address. Like wen somebody emails you from outlook.

I hope someone can understand wat i am talking about.

Thanks

i am not 100% sure but its not possible as far as i know u need to find an open relay , but i might be wrong

rbutler · Apr 11, 2005, 13:41

For showing the results like you want something like this would work:

Code:

<%@ Page Language="VB" Debug="True" %>
<%@ Import Namespace="System.Web.Mail"%>
<html>
<head>
<title>Contact Form</title>
<script runat="server">
Sub SendMail(s as Object, e as EventArgs)
    Dim objMail as New MailMessage()
    
    objMail.To="emailaddress@domain.com"
    objMail.From=txtEmail.Text
    objMail.Subject="Contact Us"
    objMail.BodyFormat=MailFormat.Text
    objMail.Body="Name: " & txtName.Text & vbcrlf
    objMail.Body &="Email Address: " & txtEmail.Text & vbcrlf
    objMail.Body &="Comments: " & txtComments.Text & vbcrlf

    SmtpMail.SmtpServer="localhost"
    SmtpMail.Send(objMail)

    txtName.Text=""
    txtEmail.Text=""
    txtComments.Text=""
    
    lblMessage.Text="The message has been sent!"
End Sub

Sub Reset(s as Object, e as EventArgs)
    'clear the contents of the form
    txtName.Text=""
    txtEmail.Text=""
    txtComments.Text=""
End Sub
</script>   
</head>
<body>
    <form runat="server">
    <table width="400" cellpadding="0" cellspacing="0" align="center">
    <tr>
        <td>Full Name:</td>
        <td><asp:TextBox id="txtName" runat="server"/>
    </tr>
    <tr>
        <td>E-mail:</td>
        <td><asp:TextBox id="txtEmail" runat="server"/>
    </tr>
    <tr>
        <td valign="top">Comments:</td>
        <td><asp:TextBox id="txtComments" TextMode="MultiLine" Rows="4" Columns="15" runat="server"/>
    </tr>
    <tr>
        <td colspan="2" align="center"><br><asp:Button id="btnSubmit" runat="server" OnClick="SendMail" Text="Submit"/>
        <asp:Button id="btnReset" runat="server" OnClick="Reset" Text="Reset"/><br>
        <asp:Label id="lblMessage" runat="server"/>
    </tr>
    </table>
    </form>
  </body>
</html>

Where the from field is a text box control that when submitted to an email client such as Outlook, hitting the reply would automatically fill in their email address. As far as authentication, not sure, I've only used relay.

NightStalker-DNS · Apr 12, 2005, 01:47

Hi

Thanks for the replies.

But i want it in outlook 2 say:
eg. From: My Name

and wen i click reply it goes to myemail@isp.com

I dnt know if this is possible. There must be some way to authenticate on a secure mail server.

if not, it would be very stupid of MS

Oh well. Thanks in advance

rbutler · Apr 12, 2005, 07:16

Then replace the to and from in the object to your settings.

Code:

objMail.To="youremail@email.com"
objmail.From="Your Name Here"

Apr 29, 2005, 07:26

dude it is giving an error

This is a good article and it worked both from local server and remote server for me but what if I want to show my name as "Some Name" and send it from a non standard port on remote or local SMTP Server :p?

xfriday · May 30, 2005, 04:58

ok I figured out the name thing and I just need to mention it as

"Some Name<someemail@some-domain.com>"

and thats all there is to it.
:-)

Cheers!!

You can check my last post

Caitriona · Jun 16, 2005, 07:14

I know this should work and it has clearly worked for others. However when I run this on my browser and enter my email address I get the following error (with line 21 highlighted)

Exception Details: System.Runtime.InteropServices.COMException: The transport failed to connect to the server.

Source Error:

Line 19: objMail.BodyFormat = MailFormat.Text
Line 20: SmtpMail.SmtpServer = " smtp.your-server.com"
Line 21: SmtpMail.Send(objMail)
Line 22: Else
Line 23: lblResponse.Text = "Please enter an email address."

(Please also note that I have configured IIs to send email and I am using the following Microsoft.net beta version --------------------------------------------------------------------------------
Version Information: Microsoft .NET Framework Version:1.1.4322.2032; ASP.NET Version:1.1.4322.2032 ).

Any help would be greatly appreciated

Aug 21, 2005, 22:12

The author forgot that most SMTP servers
need a password. So his code *VERY* rare
ever works.
Sheezesss. Great way to "teach" asp.net

Sep 8, 2005, 04:54

this requires 1.1 of .net framework, but allows authentication using smtpmail

objmail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1") 'basic authentication
objmail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "usrename") 'set your username here
objmail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "password") 'set your password here

ADACProgramming · Sep 10, 2005, 17:47

This is the entire function that I use. Just change the obvious strings. You can find one of the places I implemented this at
My directories list at http://www.adacprogramming.com/Utili...orieslist.aspx
if you want to see how it works.

string strMailBody;
strMailBody = "Directory in question: " + this.txtDirectory.Text +
"<BR>Comment

br> " + this.txtComment.Text;

System.Web.Mail.MailMessage mail = new System.Web.Mail.MailMessage();
mail.From = this.txtFromAddress.Text;
mail.To = "Anyone@someserver.com";
mail.Subject = "*******Directory List Comment********";
mail.Body = strMailBody;
mail.BodyFormat = System.Web.Mail.MailFormat.Html;

string Username = "MyUserName";
string Password = "MyPassword";

try
{
mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1"); //none, cdoBasic, NTLM

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", Username );
mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", Password );

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusing", 2);
mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport", 25);
mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpusessl", false);
mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout", 60);

string SmptServer = "mail.servername.com";
System.Web.Mail.SmtpMail.SmtpServer = SmptServer ;
System.Web.Mail.SmtpMail.Send(mail);

this.lblMessageSent.Visible = true;
}
catch{}

JakeJeck · Sep 10, 2005, 21:34

ADAC,

There's no point in using try/catch if you don't do anything when an exception occurs. Plus it wastes overhead.

Also I'd recommend putting the From Address, username, password, and smtp server name in the web.config. It's always better to modify a config file than having to modify code and recompile if things ever change.

I would normally agree with the try catch except in my code the mail portion is a secondary consideration. I also send this to a database. This just keeps a possible server glitch from showing to the user. In my complete code the error would be recorded so I would know about it.

Also agree on the web config. I use this code in several places in my website. Would be a pain to change them with out web.config.

Thanks Dwayne
