edit email account that cron uses to send out

I get the below bounce back when try to email out cron report.

Undeliverable: Cron <root@linux> /usr/bin/wget https://www.domain.info/php/cron.php >/var/www/vhosts/default/htdocs/cron-logs-1481456

The reson it's rejected is because it trys to send out using the following email address which doesn't exsist.


How do I edit the above email address so mail servers will accept it?

The change required are

(1) mailing domain name needs to be changed - some thing like  linux.domain.co.uk.

(2) add a valid forward and reverse DNS entry for domain  linux.domain.co.uk.


Your exchange needs to relay the server from which the mail is generated.

I've just replaced domain names local or external with domain.

I don't think there is a problem with the mailer-daemon, are you able to send a normal e-mail to "dan@domain.eu"?
Daniel ForresterDirectorAuthor Commented:
Yes, the mailer-daemon address isn't a correct email address that's why it rejects it.
Sikhumbuzo NtsadaSenior IT TechnicianCommented:
I see the host is using a fictional name, I don't see how we can just change the e-mail address - I think we need a new approach.

I was reading the following link - see if you can follow and let's discuss

In /etc/postfix/main.cf, what do you have for $myhostname, $myorigin, and $mydomain ?

Check out http://www.postfix.org/postconf.5.html#myhostname -- your sending server hostname and email from-domain need to be internet-resolvable, they cannot end in .local.
