I'm trying to read through a gmail account to get gps data that is being sent there ( in the text of a email) from an moble phone (my phone)

using (Pop3Client cl = new Pop3Client())
            {
                cl.UserName = "crash893";
                cl.Password = "password";
                cl.ServerName = "pop.gmail.com";
                cl.AuthenticateMode = Pop3AuthenticateMode.Pop;
                cl.Ssl = true;
                cl.Authenticate();
                ///Get first mail of my mailbox
                Pop3Message mg = cl.GetMessage(1);  <<<<<<<<<< ERROR
                String MyText = mg.BodyText;
                ///If the message have one attachment
                Pop3Content ct = mg.Contents[0];
                ///you can save it to local disk
                ct.DecodeData("c:\\test.txt");
            }

but I get a exception on the "get first mail of mailbox message 

"Higuchi.Net.Pop3.Pop3ConnectException: Pop3 connection is closed
at Higuchi.Net.Pop3.Pop3Client.SendCommand(String inCommand)
at Higuchi.Net.Pop3.Pop3Client.Execute(String inCommand, Boolean inIsMultiLine)
at Higuchi.Net.Pop3.Pop3Client.Execute(Pop3Command inCommand)
at Higuchi.Net.Pop3.Pop3Client.GetMessage(Int64 inMailIndex)"}

Ideally what i would like to do is open this read all the new unread emails in this account for a certain subject line then read the data in the body and mark them as read

does anyone know why its erroring out

does anyone have any experince with c#mail that hey could point me in the right direction for reading and makring emails as read etc

You should probably make total a long (not int), and get rid of Convert.ToInt16 - SLaks 2009-06-16 21:19

It is not possible to mark emails as read using the POP protocol.

Try using IMAP.

are you sure? how does outlook do it via pop3 - Crash893 2009-06-16 20:16
do you have a easy to use free imap client - Crash893 2009-06-16 20:54
Outlook does not do it via POP3. When you mark a message as read in Outlook, it updates a local database. The only interaction between Outlook and the POP server is to download the message in the first place - SLaks 2009-06-16 20:59
To do this using IMAP, you'll also need to reconfigure Outlook on your phone to connect to Gmail using IMAP - SLaks 2009-06-16 21:01
You can find a .Net IMAP client here: http://www.lumisoft.ee/lsWWW/Download/Downloads/Net/. Or, try searching Stack Overflow or Googl - SLaks 2009-06-16 21:05

I do not have experience with C#Mail, and this answer may not help, but I've experienced weirdness in the past while trying to write email send/receive related code.

Turned out the antivirus software we were running at work had a whitelist of allowed .EXE's that could make in/outbound POP3 or SMTP connections. Any chance this is your problem?
