The easiest (if you are indeed using sendmail) is to find /usr/src/etc/sendmail, edit the file, removing the /^dnl / from the lines that activate the MAPS features. That assumes you want to make world. If not, copy that file (/usr/src/etc/sendmail/freebsd.mc) to /usr/share/sendmail/cf/cf, make the change, 'make freebsd.cf' and copy the resulting freebsd.cf to /etc/mail/sendmail.cf and restart sendmail. joe To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
