Disabling email sending in crontab

[brumik]

In Solaris the mailto="" is unsupported.

We don't want any users on the system to recieve emails from
cronjobs , all jobs *should* redirect output to a log file (> logfile
2>&1 or /devnull) , however sometimes people or software will add
crontabs without redirecting, then we get messages like this:

ct 17 13:49:00 server sendmail[18416]: [ID 801593 mail.crit] NOQUEUE:
SYSERR(root): /etc/mail/submit.cf: line 434: readcf: option RunAsUser:
unknown user smmsp

How can we disable crontab from trying email to send output of
cronjobs? e.g. change the default to send it all to /dev/null instead
of emailing the user.

thanks

You could always add user smmsp to /etc/passwd and /etc/shadow to make those errors go away. In fact, you probably SHOULD add that user as it is part of modern sendmail configs. There were a number of bugs in Solaris patches that didn't add this user when they upgraded sendmail to later versions.
