Hello,
I would like to receive mail at "mydomain" for a few users that are not
system (unix) users. I know I can add them as system users, however, from
a security standpoint I'd rather not. How can I have postfix deliever
mail to them? Do I have to create a new local lookup table? If that is
the case, what happens to my actual system users? Do they also have to be
placed in the new local lookup table?
Just wondering, if it is a pain in the butt if I should just add them as
regular system users and be done with it...
Thanks!

You must set them up with a username/password *somewhere* so
they can check their mail. With most IMAP/POP software, that
means either creating system users or using a "virtual"
back-end such as SQL or LDAP.
The quick and dirty way is just create system users with the
login shell set to /bin/false or whatever so they can't
actually get shell access. For a small number of
somewhat-trusted users, that's the easy way to go.
Dovecot can use a "passwd-like" file (manually maintained file
with contents similar to /etc/passwd) to make local users with
no system privileges, you might want to read up on that.
