set-uid root file permissions

I just set up a new server (CentOS 6 - VM Pro) and have this post fix error:

Oct 28 10:25:01 server postfix/sendmail[16424]: warning: the Postfix sendmail command has set-uid root file permissions
Oct 28 10:25:01 server postfix/sendmail[16424]: warning: or the command is run from a set-uid root process
Oct 28 10:25:01 server postfix/sendmail[16424]: warning: the Postfix sendmail command must be installed without set-uid root file permissions
Oct 28 12:25:34 server postfix/postfix-script[2921]: fatal: the Postfix mail system is not running

Looks like it was initially running, then something happened.

My apologize for not working this a little harder before posting the question. I killed off a stubborn postfix PID, restarted and back to normal.

That’s great, I’m glad you got it figured out! Thanks for letting us know how you fixed it.

Can you elaborate on this? I have the same thing but have no idea how to find the pid and kill it… thanks

You could find postfix pid’s with something like:

ps aux | grep postfix

And then kill any pid’s you want with:

kill -9 pid#

Thanks.

When i run the ps aux | grep postfix I get this:

[root@targetmyad /]# ps aux | grep postfix
postfix 12595 0.0 0.0 78756 3216 ? S 21:20 0:00 pickup -l -t fifo -u
root 14392 0.0 0.0 103292 868 pts/0 S+ 21:53 0:00 grep postfix
postfix 21683 0.0 0.1 79692 4160 ? S Jan10 0:03 qmgr -l -t fifo -u
root 32638 0.0 0.0 78676 3232 ? Ss Jan08 0:05 /usr/libexec/postfix/master
[root@targetmyad /]#

I am a novice here with postfix… - the error that im getting may be slightly different… postfix isnt stopped on mine… I have this now:

Jan 11 21:45:02 mail01 postfix/sendmail[14018]: warning: the Postfix sendmail command has set-uid root file permissions
Jan 11 21:45:02 mail01 postfix/sendmail[14018]: warning: or the command is run from a set-uid root process
Jan 11 21:45:02 mail01 postfix/sendmail[14018]: warning: the Postfix sendmail command must be installed without set-uid root file permissions

I read that this is a cron bug… Think i have a problem with postfix or should i just ignore this?

Thanks
