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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Imap')
loImap = CreateObject('Chilkat.Imap')

* Connect to an IMAP server.
* Use TLS
loImap.Ssl = 1
loImap.Port = 993
* Use your IMAP server domain.  This example 
lnSuccess = loImap.Connect("my-imap-server-domain.com")
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* Login
lnSuccess = loImap.Login("myLogin","myPassword")
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* Select an IMAP mailbox
lnSuccess = loImap.SelectMailbox("Inbox")
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* Get message ID's for emails older than 1/1/2018

lnFetchUids = 1
loMessageSet = loImap.Search("SENTBEFORE 01-Jan-2018",lnFetchUids)
IF (loImap.LastMethodSuccess = 0) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* If desired, we can examine the Subject of each email to be deleted..
i = 0
lnCount = loMessageSet.Count
DO WHILE i < lnCount
    loEmail = loImap.FetchSingleHeader(loMessageSet.GetId(i),1)
    IF (loImap.LastMethodSuccess = 1) THEN
        ? loEmail.Subject
        RELEASE loEmail
    ENDIF

    i = i + 1
ENDDO

* Set the Deleted flag for each message:
lnSuccess = loImap.SetFlags(loMessageSet,"Deleted",1)
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loMessageSet
    RELEASE loImap
    CANCEL
ENDIF

* Expunge and close the mailbox.
lnSuccess = loImap.ExpungeAndClose()
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loMessageSet
    RELEASE loImap
    CANCEL
ENDIF

* Disconnect from the IMAP server.
lnSuccess = loImap.Disconnect()
