It IS possible to just ignore (or leave it to the logs) stuff going on in a desktop system, but services like logwatch are very helpful to maintain a healthy system.  Plus there is cron for regular tasks we like to perform.

Probably some /bin/sendmail script that maps sendmail arguments to a mailx call.  Plus if you DO install sendmail or postfix, it should undo this setup.

No.  Just trying to see what is possible.  Given that no sendmail, could 
local delivery be made to work without an MTA.

Well it got explained to me that, no.  Even local delivery needs an MTA.

So I will start with postfix, as that is what I run on my mail server 
and my other servers.

But which is the kindest to the system resources, sendmail or postfix?  
Centos switched to postfix a couple releases ago as the default MTA (as 
I seem to recall).
