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

loImap = CreateObject('Chilkat.Imap')

* Connect to an IMAP server.
* Use TLS
loImap.Ssl = 1
loImap.Port = 993
lnSuccess = loImap.Connect("imap.example.com")
IF (lnSuccess = 0) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* Login
lnSuccess = loImap.Login("myLogin","myPassword")
IF (lnSuccess = 0) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* First examine the already subscribed mailboxes.
lcRefName = ""
lcWildcardedMailbox = "*"
lnSubscribed = 1

loMboxes = CreateObject('Chilkat.Mailboxes')
lnSuccess = loImap.MbxList(lnSubscribed,lcRefName,lcWildcardedMailbox,loMboxes)
IF (lnSuccess = 0) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    RELEASE loMboxes
    CANCEL
ENDIF

i = 0
DO WHILE i < loMboxes.Count
    ? loMboxes.GetName(i)
    i = i + 1
ENDDO
? "----"

* Sample output.

* INBOX
* INBOX/recent
* INBOX/misc
* INBOX/misc/solutions
* ...
* Outbox
* Deleted Items
* Sent Items
* Drafts
* Junk E-mail
* Trash
* Sent
* Templates

* Let's unsubscribe to "INBOX/misc/solutions".
lnSuccess = loImap.Unsubscribe("INBOX/misc/solutions")
IF (lnSuccess = 0) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    RELEASE loMboxes
    CANCEL
ENDIF

* Get the list of subscribed mailboxes again to verify that "INBOX/misc/solutions" is missing.
lnSuccess = loImap.MbxList(lnSubscribed,"","INBOX/misc*",loMboxes)
IF (lnSuccess = 0) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    RELEASE loMboxes
    CANCEL
ENDIF

i = 0
DO WHILE i < loMboxes.Count
    ? loMboxes.GetName(i)
    i = i + 1
ENDDO
? "----"

* Re-subscribe to "INBOX/misc/solutions".
lnSuccess = loImap.Subscribe("INBOX/misc/solutions")
IF (lnSuccess = 0) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    RELEASE loMboxes
    CANCEL
ENDIF

* Get the list of subscribed mailboxes again to verify that "INBOX/misc/solutions" is back in the list.
lnSuccess = loImap.MbxList(lnSubscribed,"","INBOX/misc*",loMboxes)
IF (lnSuccess = 0) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    RELEASE loMboxes
    CANCEL
ENDIF

i = 0
DO WHILE i < loMboxes.Count
    ? loMboxes.GetName(i)
    i = i + 1
ENDDO
? "----"

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