[imapfilter-devel] move/copy problem

[Michael M. Tung]

Hi Lefteris:

Thank you for all your suggestions.

I guess the problem was that some text messages were empty, which gave an
'required argument left out' error. Both systems I mentioned have identical
software, but one is 32bit and the other 64bit. Maybe the byte size made a
difference in the tables and produced the different occurrence of this error?

For other people interested, I am attaching the definition of a bogofilter
function which now works fine.

Best,
      Mike

--   Bogofilter   --
--------------------

function bogo(myserver)
        print(string.format("Running bogofilter on %s...", myserver._imap.server))
        all = myserver.INBOX:select_all()
        spam = Set {}
        unsure = Set {}
        for _, mesg in ipairs(all) do
                mbox, uid = unpack(mesg)
                text = mbox[uid]:fetch_message()
                if(text ~= nil ) then
                        flag = pipe_to('bogofilter', text)
                        if (flag == 0) then
                                table.insert(spam, mesg)
                        elseif (flag == 2) then
                                table.insert(unsure, mesg)
                        end
                end
        end
        myserver.INBOX:move_messages(myserver.Junk, spam)
        myserver.INBOX:move_messages(myserver.Unsure, unsure)
end
