Experiment the antispam dovecot plugin
100%
Description
Once i founce this plugin: http://johannes.sipsolutions.net/Projects/dovecot-antispam
Unfortunately, moving many mails at once would surely drive Orfeo crazy, so i just disregarded this plugin in the past. I just found there is a spool2dir backend, which could be used to create a daemon or incron script to handle delayed retraining in order to avoid creating too much load on the machine. Maybe we could have a look and write some code.
It is now packaged in Debian.

Z-Spam test folder being used with the mail retrainer script. Using "Junk" of the like would be better for production.
Activated the expire plugin for the Z-Spam plugin, which only does a special indexing. The doveadm script must be used in a crontab to test removing old mails in the test folder. The rule could be Seen=>30d, UnSeen=>90d for example.
As for the files to flow in, to be discussed:- the default DSPAM mode could become Deliver
- a global SIEVE script (sieve_global_dir) could be provided to redirect such bad mails in
- a default SIEVE script (sieve_global_path) could be installed, including the previous global script
- advanced users may then override the behavior simply by having a custom script (in this case the default script is not run), and include the global script they wish

The script now follows our requirements. Testing more is needed bu currently satisfactory.
Created and compiled /etc/dovecot/global-sieve/scripts/incoming_spam.sieve with the temporary rules i made for my own account to get SPAM in the Z-Spam test directory. I'm now including it in my own script. Testing in progress.

Fixed dict configuration for the expire plugin. Db files where moved in a separate subdirectory where the doovecot user can write (useful for SQLite).
Commands to look for mails:
doveadm search -A mailbox Z-Spam savedbefore 7d seen doveadm search -A mailbox Z-Spam savedbefore 30d unseen doveadm search -A mailbox Z-Spam savedbefore 90d flagged

- these mails would be deleted:
doveadm search -A mailbox Z-Spam savedbefore 1d deleted doveadm search -A mailbox Z-Spam savedbefore 7d seen unflagged doveadm search -A mailbox Z-Spam savedbefore 30d unseen unflagged
- the remaining flagged mails, seen or not, would stay forever until deleted or unflagged by the user manually; the (hard) limit would be the mailbox quota
To really remove mails (purged, not just marked as deleted): s/search/expunge/

srv_autoexpire_junkbox has been created to implement such auto-purge and is now in crontab. The details can be adjusted before reaching production.

The junk folder was activated (replacing Z-Spam). The dovecot configuration was updated, and test folders renamed. the autoexpire script was updated and renamed.
The autoexpire mechanism was also documented.

Default retrain and rules activated.
As the default SIEVE behavior has changed concerning delivery into non-existing folders, which are no more auto-created, the Junk folder is now autocreated using a Dovecot plugin (but not auto-subscribed).
Waiting a week for potential problems.
