I run postfix on all of my vmware VMs with this minimal config:

/etc/postfix/main.cf -
queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
mail_owner = postfix
inet_interfaces = 127.0.0.1
recipient_delimiter = _
setgid_group = postdrop
relayhost = (my relay host)

If you wanted it smaller I just  tested it with this config and
it still works:
mail_owner = postfix
inet_interfaces = 127.0.0.1
setgid_group = postdrop
relayhost = (my relay host)

Could probably reduce it further..

I do re-route mail destined for accounts like root to a different
account on a remote system, which is configured in the aliases file.
