I am finally off of the exchange server. Still got some backup and cleanup left to do. But for the most part I am off.
Still some former business partners still using it, so it will run till it dies.
And after I get the data off, I will not worry about it.
I did figure out how to forward individual emails to a mail server using the transport settings. But I also figured out how to forward emails to another email using postfix and virtual settings.
Back is getting better, hoping to resume some sort of workout next week.
