=========================================================================== $NetBSD: MESSAGE.NetBSD,v 1.6 2015/07/26 15:53:11 bsiegert Exp $ The existing /etc/rc.d/postfix can be forced to start ${PREFIX}/sbin/postfix instead of /usr/sbin/postfix, by adding the following lines to /etc/rc.conf.d/postfix: postfix_command='${PREFIX}/sbin/postfix' required_files='${PKG_SYSCONFDIR}/main.cf' postconf='${PREFIX}/sbin/postconf' Please note that /etc/rc.conf.d/postfix does not exist by default so you need to create that file if you need to override the default settings. Remember to modify /etc/mailer.conf to use ${PREFIX}/sbin/sendmail instead of /usr/libexec/postfix/sendmail. ===========================================================================
