What it is

The list, in plain terms.

Blockedservers Spam is one of several DNS blocklists published by BlockedServers.com, a free threat-intelligence service. The spam zone (spam.rbl.blockedservers.com) lists IP addresses seen sending spam, alongside sister zones for network scanning (netscan) and Tor exit nodes (torexit).

It is a minor list. Few large receivers consult it directly and its weighting in reputation scoring is low, so a listing here rarely blocks mail on its own. It matters mainly when your IP is also on other blocklists, where it can be the entry that tips a message over a receiver's rejection threshold.

The list flags IP addresses, not domains — it is your sending server that is listed, not the domain in your message. Removal is free and self-service through the operator's own site, so there is no reason to pay anyone to clear it.

Why you get listed

What a listing on Blockedservers Spam means.

Spam sent from the IP The address was observed sending spam or abusive email traffic. This is the behaviour the spam zone tracks and the reason to check your mail logs first.

A compromised account or host A hijacked mailbox, a vulnerable web application or a malware infection on the network can send spam without your knowledge. The IP is listed for the traffic, not for anything you did deliberately.

An open relay or misconfiguration A mail server that relays for unauthenticated senders, or is otherwise misconfigured, gets used to push spam and picked up by the list.

How to get removed

Delisting, in order.

Removal is free. Fix the cause first — a listing you clear without a fix comes straight back.

1 Confirm the listing. Look your IP up at blockedservers.com. The IP information page shows which zones you are on — confirm it is the spam zone before you act, since the netscan and torexit zones point to different causes.
2 Find and fix the cause. Review your mail logs to identify what triggered the listing: a compromised user account, a vulnerable web application, a malware infection or an open relay. Change exposed passwords, apply patches and close any relay before you request removal.
3 Request delisting. On your IP information page, use the "Request Delisting" link. The site asks you to confirm the removal for that address — there is no fee, no account and no paperwork. Removal is self-service and free.
4 Re-check before resuming. The operator estimates delisting takes about five minutes. Allow that plus DNS propagation, then look the IP up again to confirm it has cleared before you ramp sending back up.

The official route

Straight to the source.

Removal happens on Blockedservers Spam's own tool — never through a paid service.

How long it takes

Delisting is self-service and the operator estimates it completes in about five minutes, plus DNS propagation before receivers see the change. If the underlying spam continues, the IP will be detected and relisted, so fix the cause before you delist.

Common questions

About Blockedservers Spam, specifically.

Does Blockedservers charge to remove my IP? No. BlockedServers.com is a free threat-intelligence service and delisting is self-service at no cost. Any third party offering to remove the listing for a fee is a scam — you can do it yourself in a couple of clicks.

How do I delist my IP from Blockedservers Spam? Look the IP up at blockedservers.com, open its information page, and use the "Request Delisting" link. Confirm the removal when prompted. Fix the cause of the spam first, or the IP will simply be relisted.

How long does removal take? The operator gives an estimate of about five minutes for the delisting itself. Add normal DNS propagation time before receiving servers stop seeing the listing.

How much does a Blockedservers Spam listing actually affect my mail? On its own, very little — it is a small list with low weighting that few major receivers consult. It matters most when your IP is also on larger blocklists, where it can push a borderline message over a receiver's rejection threshold.

Why was my IP listed when I never sent spam? The list flags the IP for the traffic seen from it, not for your intent. A compromised mailbox, an exploited web application, a malware infection or an open relay can send spam from your address without your knowledge. Check your mail logs to find the source.

I delisted but got listed again — why? Because the cause was still active. The list re-adds an IP once abusive traffic is seen again. Removal is not a fix: clean the compromise, secure the account or close the relay first, then delist.

The bounce behind the listing.

554 5.7.1 message rejected → The permanent bounce a listing most often triggers — what it means and how to clear it. 550 5.7.1 blocked → A rejection on reputation grounds — usually the same listing, seen from the sender side. Blacklist checker → Re-check your domain and every sending IP once the cause is fixed.
