Read POP3 Email over SSL

Download Chilkat Email ActiveX

A Delphi programming example discussing POP3 SSL.

// Read POP3 email over a secure SSL connection.
// This Delphi example demonstrates how to use the Chilkat email component
// to read email securely via SSL.  The programming is identical to that
// of reading over a non-SSL connection.  The only difference is that
// the mailman's PopSsl property should be set to 1, and the port number
// should be changed to 995.   Port 995 is the standard port used by POP3
// mail servers to listen for SSL connections.  If your mail server's SSL
// port is different, you should set it to the appropriate port number.
procedure TForm1.Button5Click(Sender: TObject);
var
  bundle: IChilkatEmailBundle2;

begin
  // A ChilkatMailMan2 ActiveX component was dropped onto the Delphi
  // form, and this became the Form's member variable "ChilkatMailMan21".

  // Unlock the component -- only needs to be called once in a program.
  ChilkatMailMan21.UnlockComponent('Anything for 30-day trial');

  // Set the POP3 mail server hostname, login, and password.
  ChilkatMailMan21.MailHost := 'mail.chilkatsoft.com';
  ChilkatMailMan21.PopUsername := '***';
  ChilkatMailMan21.PopPassword := '***';

  // Indicate that we are establishing a POP3 SSL connection:
  ChilkatMailMan21.PopSsl := 1;
  ChilkatMailMan21.MailPort := 995;

  // Read the entire mailbox, leaving the mail on the POP3 server.
  bundle := ChilkatMailMan21.CopyMail();
  if (bundle = nil) then
      ChilkatMailMan21.SaveLastError('errorLog.xml');

  {
    If you try to connect to a POP3 server on a non-SSL port you will get the
    following error log.  (Note, this would happen if you forget to change
    the port number to 995.)
<ChilkatLog>
<CopyMail>

</ChilkatLog>
  }

  {
    If you try to connect to a POP3 server using SSL, and your POP3 server
    is not listening at the port number (995), you will get this error
    because the connection times out:

<ChilkatLog>
