I swear, sometimes I get things into my head to fix something, only to realize that I really shouldn't have wasted my time.
Today I am working on correcting a problem with our email server. Someone “out there” can send a message to one of us “in here” and 6-12 hours later we might get the message. There is no rationale to it, it just does it. But it has been happening more frequently than I would like, and so I had to fix it.
Well after rerouting all the DNS for way too many domains, I realized that I just needed to put everything back the way it was — which I am not in the process of doing. If this thing friggen works after doing all this, I'll be amazed!
