This article is valuable for you if you are hosting a VPS or dedicated server and face frequent RBL blacklisting issues with one or a few specific RBLs.
- Kindly note that any form of frequent blacklisting is an indication of ongoing spamming issues or defective email practices by your email users for the server.
- If your email id getting password hacked or spamming hacking-related issue, then follow the given step for all your hosted email ids each email user, as mentioned at https://billing.webji.in/knowledgebase/4890/Best-steps-to-follow-to-ensure-better-email-security.html
- If an email id hack is not an issue, and you are just having regular email usages that are also causing the issue, then you shall contact the receiver and ask them to check and update you with the root cause. The issue is unrelated to the server but related to how the remote rbl dislikes your mail usage. You shall check that pattern with your receiver and have a permanent solution for what they say to your receiver for email as they are their client.
It is related to usage that needs to be investigated by you with the receiver of the email. It is not a service downtime that we can restart or fix. OR you can provide your domain name or server IP to them to have this permanent whitelisted by their anti-spam index.
In either case, an issue like this needs to be taken care of by your end as a server owner. It is not a service downtime or technical issue where your service provider can directly help, as most of the RBL blacklist temporarily your IP for emails/spam sent by your server to them.
