Topic: [Solved] DNSBL?

Hi.

It's not very clear to me, is the current config shipped with iRedOS configured to work with any of the DNSBLs out there?
I ask this because around 40% of emails received are spam, and I'm not sure how to check to see if it's working...

Thanks.

DNSBL is easy to be integrated in iRedMail/iRedOS, you just need to modify postfix main.cf, add DNSBL servers, that's all.

Re: [Solved] DNSBL?

is easy in /etc/postfix/main.cf :
add te dnsbl`s:



smtpd_recipient_restrictions = reject_unknown_sender_domain, reject_unknown_recipient_domain, reject_non_fqdn_sender,.......
      reject_rhsbl_sender dsn.rfc-ignorant.org,
      reject_rbl_client dnsbl.njabl.org,

Re: [Solved] DNSBL?

Thanks, I'll try after the rush hours.

BTW, I found out why almost half of the emails received were spam: in amavisd config SPF_PASS had a score of -10, instead of -0.001. Also, now I discard mails with a score higher than 10. Things look a lot better now. big_smile
