I have these client restrictions set in my postfix 2.2.2-2
main.cf file:

smtpd_client_restrictions =
warn_if_reject check_client_access cidr:/etc/postfix/spam_china_korea.cidr
warn_if_reject check_client_access hash:/etc/postfix/access
warn_if_reject reject_unknown_client
warn_if_reject reject_unknown_hostname
warn_if_reject reject_non_fqdn_hostname
warn_if_reject reject_invalid_hostname
warn_if_reject reject_non_fqdn_sender
warn_if_reject reject_unknown_sender_domain
warn_if_reject reject_non_fqdn_recipient
warn_if_reject reject_unknown_recipient_domain
warn_if_reject reject_unauth_destination
warn_if_reject reject_unauth_pipelining


I just received an email from 219.133.251.247, which is
in my mailbox. Now according to maillog, there was a
reject_warning for this message:

Oct 8 10:36:40 polaris postfix/smtpd[4726]: NOQUEUE: reject_warning: RCPT from unknown[219.133.251.247]: 554 <unknown[219.133.251.247]>: Client host rejected: WE REJECT SPAM FROM ASIA!!!; from=<richardse@hereinreality.com> to=<fred@mydomain.com> proto=SMTP helo=<hereinreality.com>

So my newbie questions are:

1. Why was this message still received by me?

2. Why are there 4 entries in the maillog pertaining to this message?


-Thanks
