postfix 101

[Tom Allison <tallison@tacocat.net>]

I would like to be able to set up some accounts that are 
accessable by POP only, yet have a HOME directory so that they can 
have a procmail/bogofilter configuration for each.

But I guess I need to have something like:
User, shell=/bin/false, password - disabled. (I'll manage what 
they need to of the procmail files)

Yet still have access via POP.

I am using postfix as my SMTP server.

Is there some way that I can do this without setting up each user 
in /etc/passwd.

If this goes to 80- 100 users, will this be a problem?
