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

* Connect to an IMAP server.
* Use TLS
loImap.Ssl = 1
loImap.Port = 993
lnSuccess = loImap.Connect("imap.someMailServer.com")
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    RELEASE loBounce
    CANCEL
ENDIF

* Login
lnSuccess = loImap.Login("admin@chilkatsoft.com","myPassword")
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    RELEASE loBounce
    CANCEL
ENDIF

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

* We can choose to fetch UIDs or sequence numbers.
lnFetchUids = 1
* Get the message IDs of all the emails in the mailbox
loMessageSet = loImap.Search("ALL",lnFetchUids)
IF (loImap.LastMethodSuccess = 0) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    RELEASE loBounce
    CANCEL
ENDIF

* Fetch the emails into a bundle object:

loBundle = loImap.FetchBundle(loMessageSet)
IF (loImap.LastMethodSuccess = 0) THEN
    RELEASE loMessageSet
    ? loImap.LastErrorText
    RELEASE loImap
    RELEASE loBounce
    CANCEL
ENDIF

* Loop over the bundle and display the FROM and SUBJECT of each.
i = 0
lnNumEmails = loBundle.MessageCount
DO WHILE i < lnNumEmails
    loEmail = loBundle.GetEmail(i)

    lnSuccess = loBounce.ExamineEmail(loEmail)

    ? "Subject: " + loEmail.Subject
    ? "Bounce Type = " + STR(loBounce.BounceType) + ", email address = " + loBounce.BounceAddress

    RELEASE loEmail

    i = i + 1
ENDDO

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