ANSMTP Developers Center > Using ANSMTP in ASP/ASP.NET

Introduction

ANSMTP is a SMTP component which supports all operations of SMTP/ESMTP protocols (RFC 821, RFC 822, RFC 2554). This tutorial covers the basics of sending email with ANSMTP in ASP/ASP.Net.

How to send email with SMTP server;
How to send email without SMTP server (via DNS lookup).

Installation and Deployment

You should download the ansmtp installer and install it on your machine at first. If you want to distribute or deploy ansmtp without ansmtp installer, please click here to learn more.

Set up your IIS for ASP/ASP.NET application

Firstly, you need to install ANSMTP on your server. Secondly, create a virtual directory for your asp/asp.net application on IIS. Please note that you should assign this virtual directory with permission to run script. For ASP.NET, you have to create a sub-directory named "bin" under this virtual directory, and copy "ANSMTPLib.dll" to "bin" directory. You can find "ANSMTPLib.dll" in "DOTNET Assembly" sub-directory of ANSMTP installation directory("C:\Program Files\AdminSystem.NET\ANSMTP\DOTNET Assembly"). It is a run-time library of ANSMTP for .NET. If the .aspx is under IIS root or sub-directory, so you should create "bin" under "C:\Inetpub\wwwroot", and copy ANSMTPLib.dll to "C:\Inetpub\wwwroot\bin"

Create object instance

Now, we can use ANSMTP in ASP/ASP.NET more easily. The following code demonstrates how to create object instances in ASP/ASP.NET.

[ASP]
<%
Dim oSmtp
Set oSmtp = Server.CreateObject("ANSMTP.OBJ")
%>

[ASP.NET/VB]
<%@ Page language="VBScript" AutoEventWireup="true" aspcompat=true%>
<%@ Import Namespace="ANSMTPLib"%>
<%
Sub Page_Load( sender As Object ,  e As System.EventArgs )
  Dim oSmtp As OBJClass
  oSmtp = New OBJClass()
End Sub
%>

[ASP.NET/C#]
<%@ Page language="C#" AutoEventWireup="true" aspcompat=true%>
<%@ Import Namespace="ANSMTPLib"%>
<%
private void Page_Load( object sender,  System.EventArgs e )
{ 
  OBJClass oSmtp = new OBJClass();
}
%>

How to send email?

Now, we send email in ASP/ASP.NET with the following code.

[ASP]
<%
Set oSmtp = Server.CreateObject("ANSMTP.OBJ")
oSmtp.ServerAddr = "127.0.0.1"
'If you don't have a SMTP server, use the following code
'send email via DNS lookup, ANSMTP lookups SMTP server automatically.
'oSmtp.ServerAddr = ""  
  
oSmtp.FromAddr = "test@adminsystem.net"
oSmtp.AddRecipient "Support Team", "support@adminsystem.net", 0

oSmtp.Subject = "Test"
oSmtp.BodyText = "Hello, this is a test...."
 
If oSmtp.SendMail() = 0 Then
  Response.Write "Message delivered!"
Else
  Response.Write oSmtp.GetLastErrDescription()
End If
%>

[ASP.NET/C#]
<%@ Page language="C#" AutoEventWireup="true" aspcompat=true%>
<%@ Import Namespace="ANSMTPLib"%>
<%
private void Page_Load( object sender,  System.EventArgs e )
{ 
  OBJClass oSmtp = new OBJClass();
  oSmtp.ServerAddr = "127.0.0.1";
  //If you don't have a SMTP server, use the following code
  //send email via DNS lookup, ANSMTP would lookup SMTP server automatically.
  //oSmtp.ServerAddr = "";  
  
  oSmtp.FromAddr = "test@adminsystem.net";
  oSmtp.AddRecipient( "Support Team", "support@adminsystem.net", 0 );

  oSmtp.Subject = "Test";
  oSmtp.BodyText = "Hello, this is a test....";
  
  if( oSmtp.SendMail() == 0 )
    Response.Write( "Message delivered!" );
  else
    Response.Write( oSmtp.GetLastErrDescription());
}
%>

Remarks
We usually reply emails in 24hours. The reason for getting no response is likely that your smtp server bounced our reply. In this case, please try to use another email address to contact us. Your Hotmail or Yahoo email account is recommended.
