How do I change the TTL on our MX record? I go to dnsstuff.com and notice that the TTL was 86400 seconds. The reason I want to temporarily change the TTL is that we are moving to an outsourced spam filterign solution. I want the TTL to be reduced while we make the change, so the propagation will not take that long.
We do have our own DNS server. I never had to do this before, so I wanted to make sure I do it right.
