It would be nice to have an possibility to setup-additional archive options (per account and folder) where you are able to set an time after wich mails are archived "atomatically"...
This is really needed, there is/was a plugin that did this but it was really buggy, needs to be able to set auto-archive using similar settings as retention / compacting. Some folders I am happy to compact and delete old email, others I want to keep a local archive that I can then backup to the cloud or an external NAS (Or both)
