With per-recipient policy lookup, you can achieve per-recipient white/blacklists,
basic spamassassin preferences, etc. Settings are available as global setting,
or per-domain, per-user settings. iRedMail uses it to reject blacklisted
senders and bypass whitelisted senders during smtp session to save system
resource (implemented via iRedAPD plugin
amavisd_wblist, new in iRedAPD-1.4.4.).
@storage_sql_dsn enabled in Amavisd config file by default, so
it's very easy to enable per-recipient policy lookup. Just add one line after
@storage_sql_dsn like below:
# Part of file: amavisd.conf @storage_sql_dsn = [...] @lookup_sql_dsn = @storage_sql_dsn;
Then restart Amavisd serivce.
If you don't know where Amavisd config file is, please refer to our document: Locations of configuration and log files of major components
