I am entering domain in SMTP Whitelist and it is still blocked by RBL

Sep 10 18:30:28 smtp1 postfix/postscreen[867]: NOQUEUE: reject: RCPT from [xxx.xxx.xxx.xxx]:59778: 550 5.7.1 Service unavailable; client [xxx.xxx.xxx.xxx] blocked using bl.nosolicitado.org; from=<0101016d1d15a516-aa03a45a-0724-40a2-a8d1-47d4f09dffb2-000000@subdomain.domain.com>, to=<mymail@domain.com>, proto=ESMTP, helo=<a27-162.smtp-out.us-west-2.amazonses.com>

I added subdomain.domain.com on MAILPROXI WHITELIS, Domain -> sender =subdomain.domain.com
even after rebooting the system it still keeps blocking by RLB bl.nosolicitado.org

presents the same tracking center log

NOQUEUE: reject: RCPT from [xxx.xxx.xxx.xxx]:59778: 550 5.7.1 Service unavailable; client [xxx.xxx.xxx.xxx] blocked using bl.nosolicitado.org; from=<0101016d1d15a516-aa03a45a-0724-40a2-a8d1-47d4f09dffb2-000000@subdomain.domain.com>, to=<mymail@domain.com>, proto=ESMTP, helo=<a27-162.smtp-out.us-west-2.amazonses.com>

My version of Proxmox is 6.0-4.

This is the correct procedure to release RBL locks or I need to perform another operation?

I verified that the whitelist for the RBLS only accepts IP or range, has to make this release by domain or specific email, because it has this option, but does not work when inserted.

I don't understand the question?

if you cannot whitelist on IP/CIDR basis i guess your only option is to not use postscreen by removing the rbl-entries in the mailproxy configuration.

I hope this helps!
