-C is the default, and is not actually necessary. Also, -t only works when rblsmtpd can resolve the hostname of the name server it's trying to query. For example, the spamcop servers' network used to become unavailable once in a while, and rblsmtpd would ignore the timeout, as it was trying to lookup the hostname of the dns server for the rbl list. This makes the -t argument useless at times, unfortunately. Regards, Bill
