So given that I did not use the same hostname as my registered domain, will it mean that I would need to recreated my certificates for TLS?
Also there's part of the howto such as:
configure Postfix for TLS in which postfix was configured with another hostname chosen vs. my registered domain so can I simply change myhostname parameter with my registered domain?
One last question:
typically when people use mail normally you would see them use
mail.mydomainname.com or smtp.mydomain.com for example.
I am wondering about this only cause in my mind:
I'm using 1 box to do:
Question: can I refer to my server as "mydomain.com" only? Or can I make 2 references:
192.168.0.100 www.mydomain.com myhostname
192.168.0.100 mail.mydomain.com myhostname
I'm thinking of this relative to both services running on the same box.
I am sure to some it's a silly question however, I'm only trying to understand a thing or 2 in regards to configuration and setup of the server.
So When Setting up postfix, I can use mail.mydomain.com is my line of reasoning but perhaps I'm wrong in my line of thinking... Guess that's why I'm a noob :-)
