Question Change "from"-address for cron emails

[Maximilian Füsslin]

Is there a way to change the "from"-address for cron emails?
I get messages from "root@subdomain.domain.com", but I want from address to be "root@domain.com".
My full FQDN is "subdomain.domain.com" (also the URI where the plesk panel is accessible) which is also my /etc/hostname and /etc/mailname.
Mail server is reachable from "mail.domain.com".

Is there a way to tell cron or postfix to use "root@domain.com" as sender address for cron / system emails? Otherwise my personal gmail account rejects all cron mails, because (presumably) DMARC fails...

I know I can achieve this if I pipe the output of my cron scripts to the mail command:

* * * * * mycroncommand | mail -s "my subject" -r root@domain.com target@email.com

But that feels kinda hacky...

Thank you for your help.

Hi,

You can use the MAILTO setting in your cron file or crontab:

MAILTO=me@email.com

That will send all cron job output to the designated email address.

Thank you but problem is not how to send emails via cron job, the problem is the FROM/SENDER address the emails get sent with.

Try this parameter in your cron job:
-S from=sender@mydomain.com

or use this line in your crontab file:
MAILFROM=sender@mydomain.com

Thank you! Didn't know about "MAILFROM".
