Hello Goodnight; Can you help me solve this problem blocking some domains.
The message that shows is the following:
Code:
ECDHE-RSA-AES256-GCM-SHA384: 256 CV = no: SMTP error from remote mail server after RCPT TO: <[email protected]>: 550 5.7.0 Your server IP address [17x16x-1x1-12x] does not have a valid reverse DNS entry [17x16x-1x1-12x.static.example.org]. See http://spamauditor.org/best-practices/check_dynamic_reverse_dns for more information. Protection provided by MagicSpam 2.0.18-1 http://www.magicspam.com

Is this a new server ?
If so then you will need to ask your service provider or data centre to configure RDNS at thier end.
This isn't something that can be done at your end as far as I'm aware.
