In an ASP/ASP.NET email application, if email download takes longer than the timeout value (in seconds) that the current asp page is allowed to run, user will get an error "ASP Timeout". This often happens when user has a large quantity of emails to download or user downloads emails via a slow connection. By default the timeout is set to 90 seconds, it is easy to exceed this limit.

Obviously, a solution to ASP timeout is to set ASPScriptTimeout a larger value. You may click here for details. Technically the timeout problem can be solved in this way; however, some users may get frustrated and press the stop button on the browser toolbar as he waits too long.

EAGetMail POP3 Component introduces a more intelligent method to retrieve emails in background. You should download the EAGetMail Service installer and install it on your machine at first. Then you can use MailClient.GetMailsByQueue method to send the request to EAGetMail Service, the method returns to the user immediately and the EAGetMail Service performs task in background.

To run the following example, you also need to download EAGetMail Service and install it on your machine.

The following example codes demonstrate how to download email from POP3 server in background.

// To run it correctly, please change email server, user, password, folder, file name value to yours

using System;

using System.IO; 

// Add EAGetMail namespace
using EAGetMail; 

namespace receiveemail 
    class Program 
        static void Main(string[] args) 
            // Create a folder named "inbox" under current directory
            // to save the email retrieved.
            string curpath = Directory.GetCurrentDirectory(); 
            string mailbox = String.Format("{0}\\inbox", curpath); 

            // If the folder is not existed, create it.
            if (!Directory.Exists(mailbox)) 

            MailServer oServer = new MailServer("pop3.emailarchitect.net", 
                        "test@emailarchitect.net", "testpassword", ServerProtocol.Pop3 ); 
            MailClient oClient = new MailClient("TryIt"); 

            // If your POP3 server requires SSL connection,
            // Please add the following codes:
            // oServer.SSLConnection = true;
            // oServer.Port = 995;

                // Leave a copy of message on server.
                bool leaveCopy = true; 

                // Download emails to this local folder
                string downloadFolder = mailbox; 

                // Send request to EAGetMail Service, then EAGetMail Service retrieves email
                // in background and this method returns immediately.
                oClient.GetMailsByQueue(oServer, downloadFolder, leaveCopy ); 
            catch (Exception ep)
