Description Nerijus Baliūnas 2006-09-20 16:47:51 EDT
I'm getting such messages from cron daemon:

Date: Sun, 17 Sep 2006 03:02:14 +0300
From: Cron Daemon <>
Subject: Cron <root@backup> run-parts /etc/cron.daily


Who are you?: Permission denied


Who are you?: Permission denied

In /var/log/maillog at this time:

Configuration of sendmail is default.
These messages are probably because sendmail can not determine a user when cron
Comment 1 Thomas Woerner 2006-09-21 05:27:51 EDT
Please try to call /etc/cron.daily/0logwatch by hand. If the error still occurs,
then this is no sendmail bug.
Comment 2 Nerijus Baliūnas 2006-09-21 08:33:05 EDT
Error still occurs in /var/log/maillog, but not console, when I run raid_mon,
which uses Mail command:
Mail ${RAID_ADMIN} -s 'RAID anomaly' <${DIFF_FILE}

0logwatch (it's from logwatch rpm btw) produces errors both in console and log
file. It uses sendmail -t.

If it is not sendmail bug, how can I get rid of these messages?
I don't get such messages on postfix systems.

And I get these messages in nightly logwatch email:

 --------------------- Cron Begin ------------------------ 

 MAIL sending errors 2 Time(s)


 ---------------------- Cron End ------------------------- 

 --------------------- sendmail Begin ------------------------ 





 System Error Messages:

     Who are you?: Permission denied: 4 Time(s)




 ---------------------- sendmail End ------------------------- 
Comment 3 Thomas Woerner 2007-08-01 09:00:49 EDT
Why are the mails from cron from user postmaster? THis user des not exist.
Comment 4 Nerijus Baliūnas 2007-08-01 09:53:12 EDT
Probably because Return-Path is not set, so it defaults to <>, i.e. postmaster?
The received message looks like this:

Return-Path: <>

Please try use a different user for reply massages or set an alias to another one.
Comment 6 Thomas Woerner 2007-09-24 10:25:46 EDT
This bug entry was in needinfo for some time. Closing due to user inactivity as
Comment 7 Nerijus Baliūnas 2007-09-24 16:49:00 EDT
What does it mean "Please try use a different user for reply massages or set an
alias to another one"? I cannot change Return-Path, if you mean it, as it is not
me who generates mail messages but logwatch script.
Comment 8 Thomas Woerner 2007-09-28 08:58:11 EDT
Can you please verify that your sendmail and logwatch installations are ok? Use
"rpm -Va sendmail logwatch" for this.
Comment 9 Nerijus Baliūnas 2007-09-28 09:18:32 EDT
# rpm -Va sendmail logwatch
S.5....T c /var/log/mail/statistics
S.5....T c /etc/logwatch/conf/override.conf

sendmail was recently updated to sendmail-8.14.1-4.2.fc6, and
/etc/logwatch/conf/override.conf is:
# Configuration overrides for specific logfiles/services may be placed here.
services/iptables: $iptables_host_min_count = 10
Comment 10 Thomas Woerner 2007-11-29 11:58:26 EST
Do you have the root user with uid 0 in your passwd file?
Are you getting selinux avc messages?
Comment 11 Nerijus Baliūnas 2007-11-30 07:31:44 EST

selinux is disabled.
