Postfix user restrictions help?

I want to limit some users sending and receiving outside the network
I am using the instruction from the following website
http://www.linuxtopia.org/online_bo...x_documentation/RESTRICTION_CLASS_README.html

Per the instruction I have also created to other files in the postfix directory: restricted_senders = for the email addresses of the senders I want to block from sending outside the network and local_domains
postfix completely shuts down. If anyone can tell what I may be doing wrong or has another option to limit sending and receiving to local to the domain.
Below is my main.cf with the # being what I added that doesnt work.

Any help would put some of my hair back in

[root@Server1 postfix]# vi main.cf
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions =
# check_sender_access hash:/etc/postfix/restricted_senders
permit_sasl_authenticated,
permit_mynetworks,
reject_unauth_destination
#smtp_restriction_classes = local_only
#local_only = check_recipient_access hash:/etc/postfix/local_domains, reject
smtpd_tls_auth_only = no
smtp_use_tls = yes
smtpd_use_tls = yes
smtp_tls_note_starttls_offer = yes
smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key
smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt
smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem
smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom

virtual_maps = hash:/etc/postfix/virtusertable

 

ISPconfig server

This is an ISPconfig server. I am sure that may have something to do with the general restrictions not working.

Thanks again for any help
