Hi,
I don't know, but beware that if you have TXREP configured, and you do not use -L to sa-learn, I believe you will end up making DNSBL queries for all of them.
Good catch! I did not use "-L" so far and I am pretty sure there is nothing configured but from reading then man page it will not do any harm. So I will add "-L".
Besides of this a test run really cam up with 100% single CPU usage so I doubt it is doing the queries here.
Thanks! /Christian
