POP3 Session Log

Demonstrates how the Chilkat email component keeps a log of the current POP3 session in the mailman.Pop3SessionLog property. Delphi ActiveX

uses
    Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
    Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Chilkat_TLB;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// The mailman object is used for receiving (POP3) 
// and sending (SMTP) email.
mailman := TChilkatMailMan.Create(Self);

// Set the POP3 server's hostname
mailman.MailHost := 'pop3.example.com';

// Set the POP3 login/password.
mailman.PopUsername := 'pop3_login';
mailman.PopPassword := 'pop3_password';
mailman.MailPort := 995;
mailman.PopSsl := 1;

// You can start and end POP3 sessions using Pop3BeginSession and Pop3EndSession. 
// However, these calls are optional because a connection will be established automatically 
// when a method requiring a POP3 server connection is used.

// Get the list of UIDLs for all emails in the mailbox.
