How To Read The Gmail Inbox using SMTP

Can You please Terll me How To read with IMAP.

Look at http://www.example-code.com/csharp/imap.asp
There is a lot of samples.

Sorry, wrong link. It is not free component.
Free one (and open source) you can download from http://www.codeproject.com/KB/IP/imaplibrary.aspx

OK Thanks for the Link I will try that and get back to you soon...

I downloaded The Attached code and tested its not loging in using imap.gmail.com and username password.

I do not why... If you post some code here maybe someone will help... but your information is very limited....

One thing more! did you enable IMAP on your gmail account?
could you use such protocol from outlook express or something similar?

Yes I have Enabled IMAP in my gmail account. And I have no idea about this IMAP and Retriving mail. I just downlaoded the code from the link you provided and run the sample code it failed to login and then  i tried by changing the port no to 993 which is used by outlok to interact with gmail and written in gmail docs. then it waits for so long time and no response came.

993 is the IMAP+SSL. you cannot just change the port to use it.

yes but default oprt for imap is 143 and the code uses 143 port but gmail listens to port 993 so i changed it and tried but no success.

993 it is not regular IMAP so you could not use regular IMAP for reading mail... You have to use IMAP over SSL.
Paid component (from the first link) can do this and the free one cannnot.

but what i want to say is the if that paid component is there that means they have coded for the same functanilty then why can't we. I can't afford paid components. my company don't allow us to buy the components.

Great... so you have to begin with IMAP basics... http://tools.ietf.org/html/rfc3501 and http://tools.ietf.org/html/rfc2595

I do not know how much do you earn for your coding but I guess it's not worth the price of the paid component... It's just cheaper than many hours of your work.

I know You are right. But Paid Components are not a solution of a problem in my opinion.

as far as IMAP basics is concern I know its purpose but I want to use that to read mails... So i need the example of codes for that not the theory

Someone coded them so you can be sure it's possible... ;)
With RFC you should have all data you need. But I suppose it's a lot of work if you have to use IMAP+SSL.

You have an example on codeproject (second link). But if you have to use SSL it's a much more of work. Encryption requires a lot of dumb coding.

any clues with that?

Look at http://www.openssl.org/ for SSL/TLS handling...

I don't know what to get from the above link you gave to me. what encryption needs to do here I simply need to read the gmail inbox. I have done it by using pop3 the only problem is it reads from the last mail in the inbox not from the lattest one. and i just want to fecth the unread mails. what can I do.

Yes, you have to read it. But IMAP transmission is encrypted on por 993.
Try to configure it with port 143 and then use free component. with 993 you have to decrypt transmission.

how can i configure it with 143 if the server listens to 993 then it won't be confgured with 143.

Could you read data via IMAP _without_ encryption from any client? If not - why do you expect your code can do this?

So what you suggest what should i do and if should go for any comopnent then which will be better chilkat or asposs or any other.

If you cannot disable encryption (probably you cannot) then you have to write code supporting TLS encryption and IMAP protocol. Without such code your app cannot look into mailbox.

Gmail supports encryption and ssl

even when i used pop3 then also ssl was set to true without this we can't interact with gmail inbox

here is the code I used with pop3 it works then why can't with IMAP

 try
        {
            TcpClient tcpclient = new TcpClient(); // create an instance of TcpClient


            tcpclient.Connect("pop.gmail.com", 995); // HOST NAME POP SERVER and gmail uses port number 995 for POP


            System.Net.Security.SslStream sslstream = new SslStream(tcpclient.GetStream()); // This is Secure Stream // opened the connection between client and POP Server


            sslstream.AuthenticateAsClient("pop.gmail.com"); // authenticate as client


            //bool flag = sslstream.IsAuthenticated; // check flag


            System.IO.StreamWriter sw = new StreamWriter(sslstream); // Asssigned the writer to stream


            System.IO.StreamReader reader = new StreamReader(sslstream); // Assigned reader to stream


            sw.WriteLine("USER "+ txtUserNAme.Text); // refer POP rfc command, there very few around 6-9 command


            sw.Flush(); // sent to server


            sw.WriteLine("PASS "+txtPass.Text);
            sw.Flush();


            sw.WriteLine("RETR 1"); // this will retrive your first email


            sw.Flush();


            sw.WriteLine("Quit "); // close the connection


            sw.Flush();


            string str = string.Empty;
            string strTemp = string.Empty;


            while ((strTemp = reader.ReadLine()) != null)
            {


                if (strTemp == ".") // find the . character in line
                {

                   
                    break;
                }


                if (strTemp.IndexOf("-ERR") != -1)
                {


                    break;
                }


                str += strTemp;


            }


            Response.Write(str);


            Response.Write("<BR>" + "Congratulation.. ....!!! You read your first gmail email ");
 

If it can't then please suggest me which componet will be better to purchase?

Look into RFC 3501. You can read inside how to "talk" with IMAP server. You may also look into codeproject component. In your code you have SSL supported. You can do same thing with IMAP.

can you please describe a bit more I didn't get what you want to say?

you have:

 sw.WriteLine("USER "+ txtUserNAme.Text);
 sw.Flush(); // sent to server
 sw.WriteLine("PASS "+txtPass.Text);
 sw.Flush();
 sw.WriteLine("RETR 1"); // this will retrive your first email
 sw.Flush();
 sw.WriteLine("Quit "); // close the connection

for USER, PASS, RETR and QUIT command

Connect to 995 to imap.gmail.com and issue LOGIN, SELECT, LIST and CLOSE as described in RFC3501.

What does "described in RFC3501." Means?

Thanks for your time I got the solution from pop server only here is the link:
http://www.codeproject.com/KB/cs/email_client_application.aspx

but i wold like to get the solution for imap also if some can help?
