I have an email server/aggregator which delivers locally for root, and all other emails in my domain. It sends outbound email to my isp (networksolutins) masquerading as my domain via smtp. This is with sendmail.
It does not receive email from the internet via smtp. I use fetchmail to get incoming mail from multiple email/isp's. I use procmail for local delivery and serve emails using dovecot/imap. These all work fine.
I am getting new hardware for this machine, and plan to setup centos 8, which uses postfix, not sendmail. I've been trying to provision a vm with the proper configuration, but cannot get any emails delivered to root.
Is there a pointer to a configuration guide that will help me do what I want? I have googled about 100 setups, none of which are what I'm trying to achieve. They all suggest using an alias for root to a normal user, but them that user gets all of the cron, fail2ban, etc emails, instead of delivering them to root on the local machine.
Thanks,
