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

loImapSrc = createobject("CkImap")

// Connect to our source IMAP server.
llSuccess = loImapSrc.Connect("imap.someMailServer.com")
if (llSuccess <> .T.) then
    ? loImapSrc.LastErrorText
    release loImapSrc
    return

// Login to the source IMAP server
llSuccess = loImapSrc.Login("admin@chilkatsoft.com","myPassword")
if (llSuccess <> .T.) then
    ? loImapSrc.LastErrorText
    release loImapSrc
    return
endif

loImapDest = createobject("CkImap")

// Connect to our destination IMAP server.
llSuccess = loImapDest.Connect("mail.example-code.com")
if (llSuccess <> .T.) then
    ? loImapDest.LastErrorText
    release loImapSrc
    release loImapDest

// Login to the destination IMAP server

if (llSuccess <> .T.) then
    ? loImapDest.LastErrorText
    release loImapSrc
    release loImapDest
    return

// Select an IMAP mailbox on the source IMAP server
llSuccess = loImapSrc.SelectMailbox("Inbox")
if (llSuccess <> .T.) then
    ? loImapSrc.LastErrorText
    release loImapSrc
    release loImapDest
    return
endif

// After selecting a mailbox, the NumMessages property will
// be updated to reflect the total number of emails in the mailbox:
? str(loImapSrc.NumMessages)

// The emails in the mailbox will always have sequence numbers
// ranging from 1 to NumMessages.

// This example will copy the first 10 messages.
// We'll leave it up to you to write code to copy
// the entire sequence range in reasonable size chunks.

lnMsgCount = 10

if (loImapSrc.LastMethodSuccess <> .T.) then
    ? loImapSrc.LastErrorText
    release loImapSrc
    release loImapDest
    return
endif

for i = 0 to loSa.Count - 1
