All, I need a second (or third) pair of eyes. I'm on SUSE 10.1 Beta3 and I'm trying to modify postfix' /etc/postfix/main.cf (uncommenting the header_checks line). Subsequently postfix stops working: postfix/master[15235]: daemon started -- version 2.2.6, configuration /etc/postfix postfix/cleanup[15238]: fatal: open /etc/postfix/header_checks: Operation not permitted postfix/master[15235]: warning: process /usr/lib/postfix/cleanup pid 15238 exit status 1 io postfix/master[15235]: warning: /usr/lib/postfix/cleanup: bad command startup -- throttling Permissions of /etc/postfix/header_checks are fine: # ls -l /etc/postfix/header_checks -rw-r--r-- 1 root root 16393 Jan 30 18:05 /etc/postfix/header_checks So what is postfix complaining about? /Per Jessen, Zürich
