Hi, Just looking for a pointer to a recommended tutorial on setting up Postfix as a send only service to be able to send alert emails from a home server like smartmontools drive warnings etc.
I have seen several tutorials that touch on this, but the part I'm not clear on is the FQDN setting. It's home server so it doesn't have a public domain name. If my dynamic DNS provider reaches my home server at myhome.example.com, would that be the FQDN? If this makes it easier, I do have a fully functional Postfix mail server on my website server. Is there a way for the home server to send its alert emails via the business server? Or should the home send-only Postfix send through Gmail somehow? Thanks.
