Check configuration for retention

[larsen0815]

Afaics, I have to add $config['DEFAULT_RETENTION'] = 3650; to "/etc/piler/config-site.php" and restart piler.
Edit: Or default_retention_days in "/etc/piler/piler.conf"? In general, when do I need to use which file?

Is there a way to check if this value is correctly set?

I'm thinking of something like a dedicated info page in the admin area. Just list the contents of the config array.
And/or use something like "piler --show-config" to print the config via CLI.

I found out that "/etc/piler/piler.conf" is the correct config file to use.

Retention period can be determined by...
1) SQL

SELECT DISTINCT(((retained - arrived) / 60 / 60 / 24)) AS retention_period
FROM metadata
ORDER BY retention

2) Checking a single mail

cd /var/piler/tmp
pilerget ${ID of any mail} > x.eml
pilertest -m x.eml | grep retent
