Hello. I was wondering about the possibility of extending the mail capabilities of a DNSOnly server. Seems to me to be an awful waste of resources to install DNS only onto a machine or a VPS and then not be able to further utilize the resources. I have two VPS instances and one bare metal instance of DNS Only. I'd like to set one of them up to be a backup MTA in the event the main server goes down.
I noticed during the install that DNS Only removed Postfix - in light of Exim - I get that. But does that mean that something Like Dovecot can't be installed without messing up the server? I know cPanel servers are quite easy to mess up if you don't stick with the proper RPMs..
Ultimately - I'd like to know what other features can be added to a server hosting DNS Only - without messing with the core system.
