Plans for rmilter
Rmilter had been created some years before rspamd development started. Unfortunately, it wasn't actively developed for many years so far. It has several design flaws, it uses archaic configuration system, it uses threads, it contains a lot of duplicated functions with rspamd and, finally, it has a lot of code shared with rspamd (but it's not always up-to-date however). I hasn't found anybody willing to support this code as a separate project, so I think it's a good point to stop and think of what to do afterwards.
After some thinking I've decided to reorganize rmilter project and to integrate it to the rspamd meta-project.
