Where things are placed ?
/etc/ze-filter- Configuration files;
/var/ze-filter- Let's call this the
HOME DIRor where
ze-filterdoes the most of his job. Directories inside :
cdb- static (constant) databases, opened in read-only mode by the filter : policy database, valid recipients database, bayes database, …
wdb- working databases, where the filter stores live data such as greylisting data, dns resolution, …
ze-greydb- working databases used by ze-greyd (centralized greylisting) daemon;
files- flat text and binary files generated by the filter;
bin- some small tools and scripts useful to manage the filter or the data generated by it;
dbtools- BerkeleyDB tools (ze-db_recover, ze-db_upgrade, …) compiled with the filter and with the same library version of the filter.
/var/spool/ze-filter- The filter creates, in this directory, temporary files with the contents of the messages being handled.
