On a shared hosting server, my mail server is host.domain.com.
For client virtual servers, settings for incoming and outgoing mail server is host.domain.com.
However when setting up desktop pc apps like outlook, they always default to incoming and outgoing mail server as clientdomain .com
Is there a way in dns that i can have clientdomain.com for incoming and outgoing mail server where it will still work with my mail server on a shared ipaddress so that my users dont keep complaining about having to use host.domain.com?
Why do email apps automatically want to setup as clientdomain.com knowing that on a shared hosting serve the mail server is always host.domain.com? Using clientdomain.com for incoming and outgoing works in cpanel for shared hosting, why cant i get this working on mine?
Also, if the email ssl belongs to the mail server, is having option in virtualmin to copy the clientdomain ssl certificate to postfix a good idea? It overwrites the mail servers own ssl certificate. If only a shared ip address, can you guys remove that option for virtualmin so it can’t do this?
Finally, if one accidently does click on copy to postfix/webmin/usermin from a client domain, how to we then undo that mistake in virtualmin?
Am i on the right track in saying that postfix 3.4 supports multi ssl certs with multiple domains on a single ip address now? Is this called SNI?
See the following https://serverfault.com/questions/928926/postfix-multi-domains-and-multi-certs-on-one-ip
If the stack thread is true, how do i implement this using virtualmin?
