Is this cronie the cron/crontab implementation used in RHEL9?
(If no, you can just reject this ticket.)
If yes, I think there is a bug vs what the documentation says:
man 5 crontab
in RHEL9 says:
"Note: Both MAILFROM and MAILTO variables are expanded, so setting them as in the following example works as expected: MAILFROM=cron-$USER@cron.com ($USER is replaced by the system user)"
After a lot of trail'n'error I have concluded that any $variable in the
MAILFROM=someExpression
will cause that assignment to fail/get ignored and the sender of crontab mails will fall back to the default.
Hardcoding the value (without any $variable) works, but no variable substitution will work.

The mail sent will have the default sender: user@hostname not what you specified in MAILFROM.
If I'm totally missing something here, I am happy to get enlightened.
