I have a single server (server1.host.com single static ip address 12.34.56.78) setup as follows:
1.apache (websites)
- client1.com,
- client2.com
- client3.com
2.postfix/dovecot (SMTP and IMAP)
- info@client1.com
- info@client2.com
- info@client3.com
I am not using this system as a registered dns server, all domains are obtaining dns from their own registrars.
Clients are complaining about having to use the servers own hostname in their mx records
server1.host.com
A record points to ip address 12.34.56.78
Instead, they want to be able to use
mail.client1.com
mail.client2.com
mail.client3.com
the reason for this change is because mail client apps like outlook grumble profusely when the hostname is different from the client1.com domain. Clients are having problems setting up apps on pc's and mobile phones...its a real nightmare.
Also, lots of SSL errors keep popping up because the SSL certificate belongs to host.com (the servers own domain) instead of client1.com
Is it possible to do this if server1.host.com is not a registered dns server?
They do not want to have to purchase their own ip addresses
IF so, exactly what dns records are needed to do this at client's registrar?
