[SLUG] reading mail logs

["Voytek Eymont" <lists@xxxxxxxxxx>]

I'm trying to understand some mail messages stuck in my Postfix mail queue;

koala's mail scripts pick up a default sender as 'apache@xxxxxxxxxx', but,
there is no such user or mail account on koala;


is this what's happening here:

during attempted delivery to server at mail3.yyyyy.com.au, yyyyy.com.au is
doing a lookup on koala for user 'apache@xxxxxxxxxx', and, refuses to
accept mail as 'apache@xxxxxxxxxx' doesn't exist ?
