Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

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:

  1. Spamcop
  2. Spamhaus

thanks in advance.

Spamcop requires you to view spam emails to make sure that they really are spam. I don't think they give you an option to have your mta report spam automatically.

Spamhaus offers no way to report spam to them, neither manually (like spamcop) nor automatically.

I think the reject_rbl_client is what you are looking for:

smtpd_recipient_restrictions reject_rbl_client zen.spamhaus.org, reject_rbl_client bl.spamcop.net

How is this basically different from what Ashish already has mentioned in his question? And how does this report the offending IP addresses to different DNSBLs? –  joschi Nov 3 '09 at 10:46
    
I agree with joschi's comment. –  Ashish Sharma Nov 3 '09 at 10:53
