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

loImap = createobject("CkImap")

// Connect to an IMAP server.
// Use TLS
loImap.Ssl = .T.
loImap.Port = 993
llSuccess = loImap.Connect("imap.someMailServer.com")
if (llSuccess <> .T.) then
    ? loImap.LastErrorText
    release loImap
    return
endif

// Login
llSuccess = loImap.Login("****","****")
if (llSuccess <> .T.) then
    ? loImap.LastErrorText
    release loImap
    return
endif

// Select an IMAP mailbox
llSuccess = loImap.SelectMailbox("Inbox")
if (llSuccess <> .T.) then
    ? loImap.LastErrorText
    release loImap
    return
endif

// We can choose to fetch UIDs or sequence numbers.
llFetchUids = .T.
// Get the message IDs of all the emails in the mailbox
loMessageSet = loImap.Search("ALL",llFetchUids)
if (loImap.LastMethodSuccess = .F.) then
    ? loImap.LastErrorText
    release loImap
    return
endif

// When downloading headers, each email object contains
// (obviously) the headers, but the body will be missing.
// Also, attachments will not be included.  However, it is
// possible to get information about the attachments
// as well as the complete size of the email.

loBundle = loImap.FetchHeaders(loMessageSet)
if (loImap.LastMethodSuccess = .F.) then
    release loMessageSet
    ? loImap.LastErrorText
    release loImap
    return
endif

// Loop over the email objects and display information
// about each:
i = 0
lnNumEmails = loBundle.MessageCount
do while i < lnNumEmails

    loEmail = loBundle.GetEmail(i)

    // Display the From and Subject
    ? loEmail.From
    ? loEmail.Subject

    // Display the recipients:

    for j = 0 to loEmail.NumTo - 1
        ? loEmail.GetToName(j) + ", " + loEmail.GetToAddr(j)
    next
    for j = 0 to loEmail.NumCC - 1
        ? loEmail.GetCcName(j) + ", " + loEmail.GetCcAddr(j)
    next

    // Show the total size of the email, including body and attachments:
    ? str(loEmail.Size)

    // When a full email is downloaded, we would use the
    // email.NumAttachments property in conjunction with the
    // email.GetMailAttach* methods.
    // However, when an email object contains only the header,
    // we need to access the attachment info differently:
    lnNumAttach = loImap.GetMailNumAttach(loEmail)
    for j = 0 to lnNumAttach - 1
        ? loImap.GetMailAttachFilename(loEmail,j)
        lnAttachSize = loImap.GetMailAttachSize(loEmail,j)
        ? "    size = " + str(lnAttachSize) + " bytes"
    next

    ? "--"
    release loEmail

    i = i + 1
enddo

// Disconnect from the IMAP server.
llSuccess = loImap.Disconnect()

release loMessageSet
release loBundle


release loImap
