Hello,

Since imapfilter 2.2 this can also be done (probably more elegantly)
like this:

ImapFilterDevel = account_google.INBOX:contain_field('List-Id', 'imapfilter-devel.lists.hellug.gr')
ImapFilterDevel:move_messages(account_google['mailinglists/imapfilter-devel'])

You should have a look at the list_all() and list_subscribed() methods
(see the imapfilter_config(5) man page).  They return a list of all or
just subscribed folders and mailboxes present in an account.

You can make them return all the mailboxes recursively for your mailbox,
eg

	mailboxes, _ = myaccount:list_all('', '*')
	for _, m in ipairs(mailboxes) do
	    print(m) // your code goes here
	end

The above code will just print the name of each mailbox on your account,
but you can do something more useful...
