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

loImap = CreateObject('Chilkat.Imap')

* To use a SOCKS4 or SOCKS5 proxy, simply set the following
* properties prior to connecting with the IMAP server:
* The SOCKS hostname may be a domain name or 
* IP address:
loImap.SocksHostname = "www.mysocksproxyserver.com"
loImap.SocksPort = 1080
loImap.SocksUsername = "myProxyLogin"
loImap.SocksPassword = "myProxyPassword"
* Set the SOCKS version to 4 or 5 based on the version
* of the SOCKS proxy server:
loImap.SocksVersion = 5
* Note: SOCKS4 servers only support usernames without passwords.
* SOCKS5 servers support full login/password authentication.

* Connect to an IMAP server through the SOCKS proxy.
* 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

* Select an IMAP mailbox
lnSuccess = loImap.SelectMailbox("Inbox")
IF (lnSuccess = 0) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

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

* Fetch the emails into a bundle object:
loBundle = CreateObject('Chilkat.EmailBundle')
lnHeadersOnly = 0
lnSuccess = loImap.FetchMsgSet(lnHeadersOnly,loMessageSet,loBundle)
IF (lnSuccess = 0) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    RELEASE loMessageSet
    RELEASE loBundle
    CANCEL
ENDIF

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

    loBundle.EmailAt(i,loEmail)

    ? loEmail.From
    ? loEmail.Subject
    ? "--"
    i = i + 1
ENDDO

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