1. Learn three ways to send mail
2. The example describes the use of the client. Deliverymethod = System.Net.Mail.SmtpDeliveryMethod.PickupDirectoryFromIis
3. How to set the SMTP server for native IIS
1. Learn three ways to send mail
First: Client. Deliverymethod = System.Net.Mail.SmtpDeliveryMethod.Network; 
//Pass the remote SMTP service to send the mail, the network here indicates you want to use the long-range SMTP server.  
Second: client. Deliverymethod = System.Net.Mail.SmtpDeliveryMethod.PickupDirectoryFromIis;  
//via the native SMTP server to send the email, The Pickupdirectoryfromiis here indicates that your mail will be sent through the SMTP server of the native IIS. So if you use this item, be sure to set the address of the server you want to go to on the SMTP service. This is detailed below.  
Third: client. Deliverymethod = System.Net.Mail.SmtpDeliveryMethod.SpecifiedPickupDirectory;  
// Indicates that the e-mail message is copied to the directory specified by System.Net.Mail.SmtpDeliveryMethod.PickupDirectorylocation. So that there are other programs to perform the sending of the message.  

2. The example describes using the client. Deliverymethod = System.Net.Mail.SmtpDeliveryMethod.PickupDirectoryFromIis delivers the message. The code for
(1) mail.aspx is as follows (paste directly):  

  2. <%@ page language="C #" autoeventwireup="true" codefile="Mail.aspx.cs" inherits="Mail"%> /c2>
  6. <! DOCTYPE HTML public "-//W3C//DTD XHTML 1.0 transitional//en" "http://www.w3.org/TR/xhtml1/DTD/ Xhtml1-transitional.dtd ">
  10. "http://www.w3.org/1999/xhtml" >
  12. "Server" >
  14. <title>mail to Users</title>
  18. <body>
  20. <form id="Form1" runat= "Server" >
  22. <div>
  24. <asp:label id="Label1" runat="server" text="Label" ></asp:Label>
  26. </div>
  28. </form>
  30. </body>


(2) The Mail.aspx.cs code is as follows:
Note: General companies are agents of the Internet. So if you use this item. You can only send messages to the intranet.
However, this does not mean that the item cannot send an external network message. But the reason for the agency blockade.
