How to reject addresses by TLD in Postfix?

Dear all,
I know that postfix can reject sender address by defining in mian.cf

"smtpd_sender_restrictions = hash:/etc/postfix/sender_access".

In sender_access file u can define whatever address such as

yahoo.com REJECT

My question is how can i reject the whole domain instead of full address like .jp, .ro, .my

Thank You

Use a regexp or pcre map:

Code:

/etc/postfix/main.cf:

    smtpd_sender_restrictions =
        check_sender_access      pcre:/etc/postfix/sender_access


/etc/postfix/sender_access:

    /\.jp$/           REJECT Mail from .jp not accepted
    /\.ro$/           REJECT Mail from .ro not accepted
    /\.my$/           REJECT Mail from .my not accepted

and after that i need to issue command postmap /etc/postfix/sender_access. Is it right

Never postmap for regexp or pcre tables. A postfix reload will cause postfix to read the tables immediately (or at its earliest convenience).
