Why is an MTA (exim) installed by deafult on Squeeze even if the
'Mail Server' option is not selected during installation? Does it
actually serve any purpose on an out of the box basic installation?

Yes,
It serves as local mail delivery agent for messages from cron and
other system daemons.
There are lower overhead/less feature-full replacements if you like,
but exim4 works well and has the flexibility to handle things like
sending (locally originated but non-locally destined) mail to a "smart
host" -- things that don't strictly fit into the "mail server" job
description, but are necessary all-the-same. And it can grow into a
full-fledged mail server if you ever need it.
