When no MTA is installed, How to send an email with a cronjob? I have below entry in my cronjob? My /etc/cron.d/backup file looks like this.
15 11 * * * root /root/scripts/backup.sh
Can I send this email via SMTP server?
If you decide a full blown MTA is too heavy weight in your environment on the different nodes (Postfix isn't the ideal choice for a so called null client), then have a look at ssmtp for example. It is provided by EPEL
It does exactly what you intend to do. There is another null client called msmtp
but that one isn't available being packaged for CentOS.
