Please help with syntax of sql_clause within policy_bank

[Daniel Funke]

Hi,

I want to read most settings within a policy bank from sql. I'm not sure 
with the syntax, but I tried:

$policy_bank{'IN_PRE_QUEUE'} = {
   syslog_ident              => 'amavis-prequeue',
   sql_clause  =>  { 'sel_policy' => "SELECT * FROM 
amavisd_select_policy WHERE policy_bank='IN_PRE_QUEUE' AND users.email 
IN (%k)" },
}

And here is my debug output:
