postfix not connecting to mysql

["Gerard Ceraso" <gerard@devslash.org>]

I am trying to set up postfix to use mysql, and I seem to be having a few
issues. Here are some of the errors I am getting.

May 13 10:10:39 debian postfix/trivial-rewrite[942]: warning: connect to
mysql server localhost: Can't connect to local MySQL server through socket
'/var/run/mysqld/mysqld.sock' (2)
May 13 10:10:39 debian postfix/trivial-rewrite[942]: fatal:
mysql:/etc/postfix/mysql-virtual.cf: table lookup problem
May 13 10:10:40 debian postfix/master[720]: warning: process
/usr/lib/postfix/trivial-rewrite pid 942 exit status 1
May 13 10:10:40 debian postfix/master[720]: warning:
/usr/lib/postfix/trivial-rewrite: bad command startup -- throttling

Here is a copy of my mysql-virtual.cf file.

# the user name and password to log into the mysql server
hosts = localhost
user = mail
password = secret

# the database name on the servers
dbname = mail

# the table name
table = virtual

#
select_field = dest
where_field = alias
additional_conditions = and status = '1'

any idea why it is not connecting? I have also tried using
unix:/var/run/mysqld/mysqld.sock for the server with the same results.
