Yahoo! IMAP (imap.mail.yahoo.com)

(from Wikipedia)

It is possible to get direct IMAP access without signing up for paid access nor using software like YPOPs! or FreePOPs. Yahoo! operates IMAP and secure IMAP servers (imap.mail.yahoo.com in particular), which are globally accessible. However they require a specific, non-standard IMAP command to be sent before login is done, namely: “ID ("GUID" "1")”.

This example demonstrates sending the non-standard IMAP command after connecting but before login. Lua

local chilkat = require("chilkat")

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

local imap = chilkat.Imap.new()

-- Connect to they Yahoo! IMAP server.
imap.port = 993
imap.ssl = true
local success = imap:connect("imap.mail.yahoo.com")
if not success then
    print(imap.last_error_text)
    return
end

-- Send the non-standard ID command...
local rawResponse = imap:send_raw_command("ID (\"GUID\" \"1\")")
if not imap.last_method_success then
    print(imap.last_error_text)
    return
end

-- Login
success = imap:login("myLogin", "myPassword")
if not success then
    print(imap.last_error_text)
    return
end

print("Login Success!")

-- Select an IMAP mailbox
success = imap:select_mailbox("Inbox")
if not success then
    print(imap.last_error_text)
    return
end

-- Continue with whatever you wish to do...
-- (see other examples..)

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