imapdomo is simple convenience wrapper around imapfilter that adds few more Lua functions and suggests some system to way how you can organize your mail filtering and/or migrations, etc.
The basic idea is to provide guidelines as to where to put your Lua rules separated to several basic 'actions'; and then add a script on top of it that can be conveniently called inside your crontab.
As of versions 0.0.Z, almost everything here is subject to breaking change without warnings or even announcement; let me know if you want to use this so I should be more careful.
Currently there are no plans to change this "development model".
Note that author of this script is just learning Lua, a bit here and a bit there, most of stuff is really just hacked up and ugly (especially to a trained Lua reader).
