Re: [Nagios-users] all notifications failing
Problem was indeed with the /tmp directory permissions. Reset this back to drwxrwxrwt and mail notifications work again. Thanks to Patrick and Thomas for the pointers.

Then you can look at /tmp/mail_trace.log for something like a failed open() call or for ENOPERM.

[Nagios-users] all notifications failing
Hi All my notifications are failing - no emails are being generated. Can someone confirm that it is the nagios user which sends the emails and not root. If this is the case then I seem to have created a file permissions problem on the system somehow and the nagios user cannot send mail. (This used to work until I installed php5-cli and ran a notifications script I picked up on exchange.nagios.org). Although it is not really a nagios issue if anyone knows what the temporary file is that it is trying to open - see below - please let me know. (The same issue occurs for other non-root users sending mail). Thanks.
