Hi Gert,

I don't want to ofense you, but you don't understand, or you're too much
involved in this.  I don't know exactly what statistics said, but in my
servers, more that 75% of the blocked spam is originated by users of the
ISPs with laxed anti-spam policies, not by open relays.  This is the
problem.  When I'm receiving reports that one of my users is spammer,
I'm simply closing his account.  Others don't.
