How many MX records are allowed?
I have a sitution that I am trying to set up.
I have 2 email servers that run on Windows: one is for internal purposes, the other is external purposes.
The external one will receive e-mail from the outside world, clean it up and forward it to the internal one.
There are 2 Windows Vista machines and 2 Unix (OpenSuse Linux) machines.
Since there can be only 1 email server per domain, I thought I would:
-> set up a local domain with ALL of the machines in it
-> set up a DNS server for the local domain
-> set up a MX record in the DNS server for the email
For the external machine, just have a Dynamic IP point to the Windows machine holding the external email server.
Does this sound plausible? Does this make sense?
Is it easier to set up DNS in Linux or Windows?
