Hi all,
as title.

I have configured sender_access to reject some email address and done all the commands described here:
http://www.cyberciti.biz/faq/howto-blac ... l-address/

but I continue to receive the email that I marked as REJECT

Why?

Thanks.

Post your relevant portions of your main.cf (e.g. smtpd_receipient_restrictions, and other client restriction parameters configured), sample from your sender_access file, and log snippet from delivery not blocked.

main.cf
Code:
smtpd_delay_reject = yes
smtpd_helo_required = no
smtpd_helo_restrictions =
    permit_mynetworks,
    permit_sasl_authenticated,
    #reject_non_fqdn_helo_hostname,
    #reject_invalid_helo_hostname,
    permit
# Sender restrictions:
smtpd_sender_restrictions =
    permit_mynetworks,
    permit_sasl_authenticated,
    #reject_non_fqdn_sender,
    #reject_unknown_sender_domain,
    permit
# Recipient restrictions:
smtpd_recipient_restrictions =
   permit_mynetworks,
   permit_sasl_authenticated,
   #reject_unauth_pipelining,
   #reject_non_fqdn_recipient,
   #reject_unknown_recipient_domain,
   reject_unauth_destination,
   check_sender_access hash:/etc/postfix/sender_access,
   reject_rbl_client zen.spamhaus.org,
#   reject_rbl_client bl.spamcop.net,
#   check_policy_service unix:postgrey/socket,
   permit

smtpd_sasl_auth_enable = yes
broken_sasl_auth_clients = yes
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_sasl_security_options = noanonymous


sender_access:
Code:
google.com                          OK
aesha9years@gmail.com               REJECT
lolylol88@gmail.com                 REJECT


Log does not log anything regarding the problem since the email is not blocked at all.
I added one of my email address to the sender_access REJECT and than tryed to send me the email from my external mail address to the one managed from my vps, the email is correctly delivered.

Have you run postmap after updating your sender_access file?
Code:
# postmap /etc/postfix/sender_access

You have permit_sasl_authenticated before your check_sender_access in smtpd_recipient_restrictions, so if you are connecting with SASL the sender_access restrictions don't get checked.
