Still working on cron without sendmail. I am learning some as I peel the onion. The latest error message is:
Jan 19 16:21:23 lx120e.htt-consult.com run-parts[22838]: (/etc/cron.daily) finished prelink Jan 19 16:21:23 lx120e.htt-consult.com anacron[10446]: Job `cron.daily' terminated (mailing output) Jan 19 16:21:23 lx120e.htt-consult.com anacron[10446]: Can't find sendmail at /usr/sbin/sendmail, not mailing output
I can't find where anacron specifies sendmail.
cat /etc/logwatch/conf/logwatch.conf # Local configuration options go here (defaults are in /usr/share/logwatch/default.conf/logwatch.conf) mailer = "/usr/bin/mailx -s Logwatch"
and
cat /etc/sysconfig/crond # Settings for the CRON daemon. # CRONDARGS= : any extra command-line startup arguments for crond CRONDARGS=-m "/usr/bin/mailx -t"
Note that in this file the quoted mailx for -m. Without the quotes, the -t was used as a crond parameter, which is an error.
