So I am currently running CentOS 6 and trying to figure out how to get Google Apps (gmail) to work. I am completely new to mail server software but have a general idea of how it works. What software do you guys recommend running on the server? What would I need to configure to get it to work?
Also I am using a DNS service (Rage4) and need to setup the PTR records. I know the record value, TTL and priority. However, it is also prompting me for a "name" (xxx.domain.com). What would I have to put there? Does this even matter?
Any help would be greatly appreciated!
