Hi.
Since a couple of months ago I’m getting a mail error everyday form the NS server:
/etc/cron.daily/0yum-daily.cron:
Failed to send an email to localhost: {'root@ns.mydomain.myltd': (450, '4.1.8 <root@mydomain.myltd>: Sender address rejected: Domain not found')}
Note: ‘ns.mydomain.myltd’ is NS’s fully qualified domain name.
I think that is related to yum failing to report about automatic updates. This is my configuration in ‘Software Center’:
I have mail server installed in NS, but just to receive mail from the internet and transmit it to my internal Zimbra server (‘Relay to another server’).
Also if I try to send a test mail to root from command line:
echo 'Subject: test' | grep sendmail root
I receive the mail in inbox as it would happen to any other of my internal servers.
I would like to get properly notified when there are updates available and when they are applied.
