After you do a fetchtext() you have a copy of the message locally.  You can
then edit the message, which is actually a Lua string, in any way you like, and
then store the modified version to the server (don't forget to delete (or
better move to a backup mailbox) the old version).

A store() function doesn't exist right now (I'll probably add one soon),
but here is one that you could use (define this function before using
it):

	function store(account, mbox, message, flags, date)
		checktype_aux(account, 'table')
		checktype_aux(mbox, 'string')
		checktype_aux(message, 'string')
		checktype_aux(flags, 'table')
		checktype_aux(date, 'string')

		if (ifcore.login(account) ~= true) then
			return
		end

		for k, v in ipairs(flags) do
			if (string.lower(v) == 'recent') then
				table.remove(flags, k)
			end
		end

		local f = ''
		if (table.getn(flags) ~= 0) then
			f = '\\' .. table.concat(flags, ' \\')
		end
		
		local r = ifcore.append(account, mbox, message, f, date)

		return r
	end


And here is an example:

	results = match(myaccount, 'INBOX', myfilter)
	text = fetchtext(myaccount, 'INBOX', results)
	fast = fetchfast(myaccount, 'INBOX', results)

	-- here you edit a message, for example message 2 (ie. the text[2]
	-- string) and then:

	store(myaccount, 'INBOX', text[2], fast[2]['flags'], fast[2]['date'])


Of course, one could write a more (or less) complicated and useful
store() command to do the job.
