Enable "Exim Configuration" in DNSONLY
For those of us who host cPanel instances in a public cloud provider like AWS, our machines are prohibited from sending outbound SMTP directly and must rely on a smarthost. Exim's config on a DNSONLY instance can be manually updated to have outgoing mail routed to a smarthost, but the changes get wiped out when cPanel upgrades are applied. This is a problem since we have to keep going in to apply the smarthost routing in order to receive important server status and security alerts.
Exim's routing is configurable in the UI on a full blown cPanel installation, which preserves the sections modified upon upgrade and I'd like to see this brought into DNSONLY
