Domain Name MX record
Posted on 2011-03-07
I have setup an new SBS 2008R2 server. With this version you only can have the internal domain name with 15 characters. So now the "Internet" external domain name is now different from the internal ... what do I put as the MX and\or reverse lookup records to. Let's say the company name is ACSCompanyLimited, during the setup of the SBS server it will only allow me to put the domain name of ACSCompanyLimit so lets so I put the internal domain name as ABC.local. After the inital setup of the SBS server, you also choose to setup the internet and external domain name. That would be ACSCompanyLimited.com. In 2003 and earlier version of 2008 we were able to have both internal and external the same, so what do I put the reverse lookup to. hostname.abccomputerlimited.com or hostname.abc.com.
