O.K. This is something I have not been aware of. As far as MTA's on any 
system I am somewhat of a newbe. I do get regular e-mails to the root 
accounts of my
various (four) systems when they are running constantly, (two are) and 
I have been wondering how a switch over will effect that.
I will need to do a system specific configuration of postfix and define 
system specific aliases, prevent public use of the servers for open 
relaying and such. So I
expect for a first timer I have my work cut out for me.
Thanks for the info, much appreciated.
