Thanks
firsttime,setting bad user

/etc/postfix/main.cf
    smtpd_sender_restrictions =
        check_sender_access hash:/etc/postfix/sender_
reject_addr_check
/etc/postfix/sender_reject_addr_check
    badu...@example.com REJECT

It's working well, baduser will be reject, after that, setting
"IP_match_domain" restrictions

/etc/postfix/main.cf
    smtpd_sender_restrictions =
        check_client_access cidr:/etc/postfix/enforce_ip_
match_domain
    smtpd_restriction_classes =
        example
    example = check_sender_access hash:/etc/postfix/example.domain
        reject
/etc/postfix/enforce_ip_match_domain
    IP    example
/etc/postfix/example.domain
    example.com    OK

Then This IP only can use @example.com as the sender address, at this time,
can not reject badu...@example.com send mail. If I disable
"IP_match_domain" restrictions, It's working again. So, I really want these
two restrictions working together

Thank you very much
Tom
