The trick is to use only part of qmail-ldap. So using qmail-smtpd and qmail-verify but not the backend part. Anotherthing that needs some consideration is to make qmail-smtpd parse a different locals file. Currently I think it would be possible by using some sort of chroot hack. I'll probably add a way to have additional domains checked by qmail-verify. -- :wq Claudio
