I am using Ubuntu 18.10 and have added a short script to anacrontab. Now I get this log warning from Anacron:
Can't find sendmail at /usr/sbin/sendmail, not mailing output
I use the default Postfix for mail rather than sendmail and I receive messages from other utilities (printer jobs, usb connected etc) via the usual Gnome messages. Why is Anacron insisting on sendmail, and do I have to install sendmail just for Anacron?
