Does anyone ever received emails from the cron daemon? The transmission of cron script error messages per email doesn’t seem to work (script error never get sent to my email, no corresponding log entry anywhere). Is the appropriate option BUSYBOX_CONFIG_FEATURE for Crondaemon activated? The sendmail command is working perfectly fine over the ssmtp package. Cron send mail over the virtual lxc host (ubuntu) perfectly fine.
Found answer myself:
according to this file, the used vixie-cron daemon look for sendmail in /usr/lib, where the openwrt packages don’t install sendmail.
so after creation of a softlink, it works
