Lua Requires Chilkat v11.0.0+

IMAP Download All Email One at a Time

Demonstrates how to download every email in an IMAP mailbox one at a time as a MIME string or as an email object. (The MIME contains the full contents of the email including all attachments.) Lua

    -- In the following call to loadlib, change the path (./chilkat.dll) to the relative or absolute directory where the chilkat.dll, chilkat.so, or chilkat.dylib is located.
    chilkat = assert(package.loadlib("./chilkat.dll", "luaopen_chilkat"))()
    print(chilkat._VERSION)

    local success = false

    local imap = chilkat.newImap{}

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

    --  Connect to an IMAP server.
    --  Use TLS
    imap:setSsl(true)
    imap:setPort(993)
    success = imap:Connect("imap.example.com")
    if success == false then
        print(imap:LastErrorText())

    end

    --  Login
    success = imap:Login("myLogin","myPassword")
    if success == false then
        print(imap:LastErrorText())

    end

    --  Select an IMAP mailbox
    success = imap:SelectMailbox("Inbox")
    if success == false then
        print(imap:LastErrorText())

    end

    --  Once the mailbox is selected, the NumMessages property
    --  will contain the number of messages in the mailbox.
    --  You may loop from 1 to NumMessages to
    --  fetch each message by sequence number.

    local bUid = false

    local n = imap:NumMessages()
    for i = 1, n do

        --  Download the email by sequence number.
        local mimeStr = imap:FetchSingleAsMime(i,bUid)

        --  ... your application may process each MIME string...
    end

    --  An alternative is to download each email in the form of an
    --  email object, like this:
    local email = chilkat.newEmail{}
    for i = 1, n do

        --  Download the email by sequence number.
        success = imap:FetchEmail(false,i,bUid,email)

        --  ... your application may process the email object...

    end

    --  Disconnect from the IMAP server.
    success = imap:Disconnect()
