[SATLUG] postfix set up

[Todd W. Bucy]

I am setting up my home email server ussing the following tutorial:
http://flurdy.com/docs/postfix/#config-simple-mta

I am currently at the point where I am configuring postfix to use mysql
and am creating the /etc/postfix/mysql_mailbox.cf

tutorial example:

user=mail 
password=mailPASSWORD 
dbname=maildb 
table=users 
select_field=maildir where_field=id 
hosts=127.0.0.1 
additional_conditions = and enabled = 1

my first question: Am I right in assuming that there needs to be an
entry for each user in this file?

example:
user=user1 
password=user1_password 
dbname=maildb 
table=users 
select_field=maildir where_field=id 
hosts=127.0.0.1 additional_conditions = and enabled = 1

my 2nd question: Is this also true for the mysql_aliases.cf and
mysql_domains.cf files as well?  the tutorial is a bit ambiguous about
this.

Thanks in advance
Todd
