How can a linux box be set up to send service emails from ' "service name" @ "machine id" ' to a non-root email account?
Example1:
to: manager@mail.com
from: cron@machine**1**.com
Example2:
to: manager@mail.com
from: mdadm@machine**2**.com
Services set up email notices with idiomatic syntax. Checking just
grep -Eir "(MAILADDR|MAILTO|-m)(\ )*(=)?(\ )*root" /etc/*
turns up Recipients:
/etc/anacrontab:MAILTO=root
/etc/cron.d/0hourly:MAILTO=root
/etc/crontab:MAILTO=root
/etc/mdadm.conf:MAILADDR root
/etc/smartmontools/smartd.conf:DEFAULT -a -n standby,7,q -S on -m root -M exec /usr/libexec/smartmontools/smartdnotify -n standby,10,q
/etc/sysconfig/smartmontools:# smartd_conf_opts="-H -m root"
(There probably are other ways - in addition to MAILADDR, MAILTO & -m - that packages name the notification recipient.)
Sender
root?
Is finding/changing those files the way to get them to mail to manager@mail.com? An account alias maybe?
Is it possible to set the sender to service@machineId?
Is creating a user and/or local mailbox required for "send only"s?

#root: marc in /etc/aliases followed by newaliases looks like the answer to me @BiG_NoBoDy
When I try it out, & it works, I'll credit you and close the q.
