for i := 0 to email.NumAttachments - 1 do
  begin
    Memo1.Lines.Add(email.GetAttachmentFilename(i));
  end;

//  Let's say we want to save the 1st attachment as "pic.jpg",
//  and the 2nd attachment as "cover.doc".
//  Call SetAttachmentFilename for both:
email.SetAttachmentFilename(0,'pic.jpg');
email.SetAttachmentFilename(1,'cover.doc');

//  The SaveAttachedFile method allows you to specify the directory
//  where the attachment is saved.  To save to the current working
//  directory, pass a "." for the directory path.  This code
//  saves each attachment to the current working directory:
email.SaveAttachedFile(0,'.');
email.SaveAttachedFile(1,'.');

//  Alternatively, we could save all the attachments in a single
//  call.  The argument to SaveAllAttachments is the directory
//  path.  In this case, the filenames set by SetAttachmentFilename
//  are used:
email.SaveAllAttachments('myAttachments');
