does dnsblog have a log map/filter/somesuch? or does the capability exist elsewhere in postfix?
currently, with spamhaus dqs in the rbl/dnsbl mix, dnsblog spits out, e.g. /var/log/postfix/postfix.log:Jun 9 13:27:56 ms postfix/dnsblog[5378]: addr 72.43.215.122 listed by domain <ACCTID>.zen.dq.spamhaus.net as 127.0.0.4 i send logs to a central log server, & simply want to anonymize -- i.e., remove/obfuscate the <ACCTID> -- from the logs. it can be done externally to postfix; within postfix config (map?), would be nice.
