Yes, this is correct and very much the UNIX model. Systems wishing to
send mail should use the mail transport agent installed on the machine
which the system administrator has already configured to work properly
in that environment. Don't know how this would work on a Billyware box
since you may not have sendmail/qmail/postfix/whatever installed.
Doesn't Outlook connect to a remote mail transport agent on the ISP
through port 25?
