use net-mail/qmail-qfilter (http://untroubled.org/qmail-qfilter/) . add it as a qmail-queue replacement and write a filter script (in any language you want) that does what you want. the filter script takes the email from STDIN and writes it to STDOUT, IIRC. instead of only blocking the BCCs, i'd block the whole mail, so that your users notice the mistake. do so by setting an appropriate return value. good luck! regards Thilo
