mmm...di sendmail.cf nya ditambain script seperti ini :
Kjunk hash -a@JUNK /etc/mail/deny
# check for junk domain/spammers
Sjunk
# lookup domain in database
R$*<@$+> $:$1<@$(junk $2$)>
# exists? return
R$*<@$*@JUNK> $@$1<@$2@JUNK>
# lookup address in database
R$*<@$+> $:$1<@$(junk $1@$2 $:$2$)>
# exists? return
R$*<@$*@JUNK> $@$1<@$2@JUNK>
# remove one subdomain, try again
R$*<@$-.$-.$+> $: $>junk $1<@$3.$4>
note. setiap spasi dipisah dengan TAB
lalu buat file database spammers di direktori tertentu eg. /etc/mail/deny
nahh nanti di file deny diisi spt:
[EMAIL PROTECTED] "551 dasar tengik.."
kalo udah jalanin perintah ini :
# makemap hash /etc/mail/deny.db < /etc/mail/deny
setelah itu mungkin anda perlu merestart sendmail killall -9 sendmail
; sendmail -bd -q5m
okeh...gitu aja..
mmm...udah..
Best Regards,
Akbar..
