Restricting what users can send mail to off-site destinations

hi,
I am trying toconfigure postfix for "Restricting what users can send mail to off-site destinations" have gone through the http://www.postfix.org/faq.html#relay_restrict
but i am getting error as "Jan 23 16:37:38 caere postfix/smtpd[22999]: fatal: restriction class `local_only' needs a definition"

have done as :

/etc/postfix/main.cf:
smtpd_recipient_restrictions =
check_sender_access hash:/etc/postfix/restricted_senders

smtpd_restriction_classes = local_only
local_only = check_recipient_access hash:/etc/postfix/local_domains, reject

and in :

/etc/postfix/restricted_senders:
foo@domain1 local_only
bar@domain2 local_only

and,

/etc/postfix/local_domains:
this.domain OK matches this.domain and subdomains
that.domain OK matches that.domain and subdomains


please advice dint find anything similar for my setup.

 

Did you run

Code:

postmap /etc/postfix/local_domains

and restart Postfix afterwards?

 

Hi falko ,this has been done and file local_domains.db created.
i dont know what was wrong but after restarting postfix this error has been gone but after that all the user's were blocked so i added "user@domain ok" in the restricted_senders file for all the required users.
and finally these users can mail (relay) offside now.
do i have to run postmap for restricted_sender too ?
i have done postmap for restricted_senders too.
Thanks

 

You must run postmap for all hash files in your main.cf (e.g. local_only = check_recipient_access hash:/etc/postfix/local_domains, reject).
