I suspect this is a safety net -- you really really don't want the 
incoming Sendmail process to allow ETRN for any hosts, because ETRN 
would result in message being delivered to the host directly from, bypassing MailScanner completely.

It's in the initscript for MailScanner so you don't have to remember to 
put it in the privacy options and rebuild the .cf file when you install

Yes -- but only for the incoming Sendmail process, the outgoing process 
will use whatever is configured in the .cf file.
