I have a Postfix e-mail receiving server setup.
I have applied the following setting in my Postfix main.cf file:
smtpd_recipient_restrictions = reject_unauth_destination, reject_rbl_client sbl-xbl.spamhaus.org, reject_rbl_client bl.spamcop.net permit
for checking the mails with DNSRBL providers.
I want to know if a certain IP address is continuously attacking with spam on my e-mail server, then how can I get it added with the following DNSRBL provider list:
thanks in advance.
