Delphi DLL Requires Chilkat v11.0.0+

Delete All IMAP Email

Demonstrates two ways to delete all email in a mailbox on an IMAP server. Delphi DLL

var
success: Boolean;
imap: HCkImap;
messageSet: HCkMessageSet;
i: Integer;
n: Integer;

begin
success := False;

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

imap := CkImap_Create();

//  Turn on session logging:
CkImap_putKeepSessionLog(imap,True);

//  Connect to an IMAP server.
//  Use TLS
CkImap_putSsl(imap,True);
CkImap_putPort(imap,993);
success := CkImap_Connect(imap,'imap.example.com');
if (success = False) then
  begin
    Memo1.Lines.Add(CkImap__lastErrorText(imap));
    Exit;
  end;

//  Login
success := CkImap_Login(imap,'myLogin','myPassword');
if (success = False) then
  begin
    Memo1.Lines.Add(CkImap__lastErrorText(imap));
    Exit;
  end;

//  Select an IMAP mailbox
success := CkImap_SelectMailbox(imap,'Inbox.RubyMail');
if (success = False) then
  begin
    Memo1.Lines.Add(CkImap__lastErrorText(imap));
    Exit;
  end;

//  Get the complete set of Uids for email in the selected mailbox.
messageSet := CkMessageSet_Create();
success := CkImap_QueryMbx(imap,'ALL',True,messageSet);
if (success = False) then
  begin
    Memo1.Lines.Add(CkImap__lastErrorText(imap));
    Exit;
  end;

//  Set the Deleted flag for each message.
//  (ExpungeAndClose must be called to finalize the delete.)
success := CkImap_SetFlags(imap,messageSet,'Deleted',1);
if (success = False) then
  begin
    Memo1.Lines.Add(CkImap__lastErrorText(imap));
    Exit;
  end;

//  Alternatively, the Deleted flag may be set for each UID
//  individiually, but this is less efficient:
i := 0;
n := CkMessageSet_getCount(messageSet);
while i < n do
  begin
    success := CkImap_SetFlag(imap,CkMessageSet_GetId(messageSet,i),CkMessageSet_getHasUids(messageSet),'Deleted',1);
    if (success = False) then
      begin
        Memo1.Lines.Add(CkImap__lastErrorText(imap));
        Exit;
      end;
    i := i + 1;
  end;

//  Expunge and close the mailbox.
success := CkImap_ExpungeAndClose(imap);
if (success = False) then
  begin
    Memo1.Lines.Add(CkImap__lastErrorText(imap));
    Exit;
  end;

//  Display the session log.
Memo1.Lines.Add(CkImap__sessionLog(imap));

//  Disconnect from the IMAP server.
success := CkImap_Disconnect(imap);

CkImap_Dispose(imap);
CkMessageSet_Dispose(messageSet);
