Question

POP3 Mail Monitor

Asked by: bubbles

I want to create a program that resides in the System Tray and checks for mail on a POP3 server at set intervals and displays a list of messages. I have seen programs similar on the Net but I am wanting some good source code to start with so I can develop the application I want. I am using Delphi 5. Any help will be much appreciated.

use TNmPop3 to receive email

Basically I am after some source code for a program that can monitor a POP3 mailbox - that's the bit I am really keen to see as I have done a bit of mucking around myself and seen that it will take quite a bit to create something robust. If there was some source code already out there that I could add to, I could convert it to work in the tray and do all the other things I wanted. I am relatively new to Delphi with a long background in VB, so part of the reason I want the source code is to learn from it.

You could do that with the Indy 9 components. It's not that hard to use them. You need code to put an icon in the trayicon, a timer that will activate an event that checks for new email and a way to store accountname(s) and password(s) in a secure place, preferably encrypted.

Indy can be found at http://www.nevrona.com/Indy/ and yes, it also works in Delphi 5. I use it for a console mailreader that will read the server, download all emails and save them to a file. It's just one *.dpr that opens some data-files containing information about my mailbox accounts. The whole code to read it is like this:
<quote?
  POP3.Connect;
  try
    Count := POP3.CheckMessages;
    if (Count > 0) then begin
      WriteLn(Log, '    - Number of messages: ', Count);
      WriteLn(AccountText, 'Number of messages: ', Count);
      for I := 1 to Count do begin
        Size := POP3.RetrieveMsgSize(I);
        WriteLn(Log, '    - Message ', I, ' is ', Size / 1024: 0: 1, ' KB.');
        WriteLn(Log, '    - Message ', I, ' is ', Size / 1024: 0: 1, ' KB.');
        WriteLn(AccountText, 'Message ', I, ' is ', Size / 1024: 0: 1, ' KB.');
        if (Size <= 0) then begin
          WriteLn(Log, 'Message is empty.');
        end
        else begin
          RawMail := TStringList.Create;
          try
            POP3.RetrieveRaw(I, RawMail);
            AssignFile(Raw, LegalFileName(InboxPath, Now));
          except
            RawMail.Free;
            raise;
          end;
          Rewrite(Raw);
          Write(Raw, RawMail.Text + EOM);
          CloseFile(Raw);
          RawMail.Free;
          POP3.Delete(I);
        end;
      end;
      WriteLn(AccountText, StringOfChar('=', 80));
    end
    else begin
      WriteLn(Log, '    - No messages.');
      WriteLn(AccountText, 'No messages.');
    end;
  except
    on E: Exception do WriteLn(Log, '      Error: ', E.Message);
  end;
  POP3.Disconnect;
</quote?
Well, there is more code but this is the reading-part. It reads the mailbox and saves the email to file while deleting it from the mailbox.

Thanks - was hoping for more complete code to do what I want, but this points in the right direction.
