Delphi DLL Requires Chilkat v11.0.0+

IMAP Download All Email One at a Time

Demonstrates how to download every email in an IMAP mailbox one at a time as a MIME string or as an email object. (The MIME contains the full contents of the email including all attachments.) Delphi DLL

var
success: Boolean;
imap: HCkImap;
bUid: Boolean;
mimeStr: PWideChar;
i: Integer;
n: Integer;
email: HCkEmail;

begin
success := False;

imap := CkImap_Create();

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

//  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');
if (success = False) then
  begin
    Memo1.Lines.Add(CkImap__lastErrorText(imap));
    Exit;
  end;

//  Once the mailbox is selected, the NumMessages property
//  will contain the number of messages in the mailbox.
//  You may loop from 1 to NumMessages to
//  fetch each message by sequence number.

bUid := False;

n := CkImap_getNumMessages(imap);
for i := 1 to n do
  begin

    //  Download the email by sequence number.
    mimeStr := CkImap__fetchSingleAsMime(imap,i,bUid);

    //  ... your application may process each MIME string...
  end;

//  An alternative is to download each email in the form of an
//  email object, like this:
email := CkEmail_Create();
for i := 1 to n do
  begin

    //  Download the email by sequence number.
    success := CkImap_FetchEmail(imap,False,i,bUid,email);

    //  ... your application may process the email object...

  end;

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

CkImap_Dispose(imap);
CkEmail_Dispose(email);
