How to whitelist an email address has been blocked by zen.spamhaus.org

[tonyng20493]

Hi all,

We are running PMG 8.1.2. and enable zen.spamhaus.org RBL. Today, we found that an email address has been blocked by zen.spamhaus.org but we need to receive it.

We try to whitelist the email address (e.g. for@example.com) and it's IP address (e.g. 1.2.3.4) on the whitelist:
Configuration, Mail Proxy, Whitelist
Mail Filter, Who Objects, Whitelist

But PMG still blocked the email with the below message:

postfix/postscreen[1715417]: NOQUEUE: reject: RCPT from [1.2.3.4]:25139: 550 5.7.1 Service unavailable; client [1.2.3.4] blocked using zen.spamhaus.org; from=<for@example.com>, to=<me@example.net>, proto=ESMTP, helo=<example.com>

How can we whitelist/avoid the email has been blocked by RBL? Please help!

Many thanks!

Tony

you need to allow the IP-address on the Mail Proxy Whitelist- and potentially to reload postfix on the commandline (postfix only reads it's config files asynchronously, so updates might not be picked up right away)

Hi Stoiko,

Thanks for your reply! Do you mean add the "IP address" on "Configuration, Mail Proxy, Whitelist" and then run:

systemctl reload postfix

Am I correct? Thanks!

Best Regards,
Tony
