Folks,
A little Linux unrelated (but I suppose it is since I am using a Linux
server) but I have been having some discussions with a number of vendors
around the place regarding secondary MX records.
There seems to be two camps here - those that do not believe that they
are needed (and thus don't provide them) and those that believe that
they are a mandatory part of a redundant mail system.
I am sitting on the fence (I can see some merits to both sides of the
argument) but I was wondering what the opinion of the sluggers out there
is - would you install one and why ?
The choice basically comes down to if you want
to control the robustness of your network or
if you are happy for other people's decisions
to control the robustness of your network.
Obviously, the more essential the network becomes
to your operations then the more you want to
have control over the network's robustness.
If you are asking this as you might be thinking
of deploying a secondary, then it's an interesting
thought that a DNS secondary and a MX secondary can
be on a different network, such as at a friendly
site or at a colocation provider.
