Package: cron
Version: 3.0pl1-128+deb9u1
Debian/Ubuntu's cron version doesn't support setting MAILFROM to set the
"From:" header of cron generated emails. This feature would be nice to
have and bring parity with RHEL/CentOS which has it since RHEL 6:
$ cat /etc/redhat-release
CentOS release 6.6 (Final)
$ man 5 crontab | grep -1 FROM
doesn´t do aliasing, and UUCP usually doesn´t read its mail. If MAIL-
FROM is defined (and non-empty), it will be used as the envelope sender
address, otherwise, ‘‘root’’ will be used.
This bug was created first under ubuntu launchpad, but as the package
is maintained in Debian project i open this bug issue.
for Ubuntu the report and comments is here:
https://bugs.launchpad.net/ubuntu/+source/cron/+bug/1750051
a patch has been submitted too
