You could try one of the goodrcptto patches to qmail-smtpd. We have one we use for gateways to exchange servers. Basicly, you export a list of users to a file. Put that file on the gateway machines. With our patch we build a goodrcptto.cdb file. Then qmail-smtpd checks the cdb file and rejects it if it does not exist.
thanks. static db's just won't work - too many customers adding/deleting email addresses throughout the day. it needs to be a 'live' lookup of what's on the systems. plus, i thought all the goodrcptto systems broke catchalls?
