What is abuse.ro Realtime Block List (RBL)?

The abuse.ro Realtime Block List (RBL) is an IP-based DNS blocklist that identifies IP addresses and network classes known for sending spam. It operates based on a policy of listing sources that send unsolicited email to its network of spamtraps, which are email addresses created specifically to attract spam. The last IP address in the email headers before the destination is the one that gets added to this blacklist.

Mail server administrators use this blocklist to help filter incoming email. It is important to note that abuse.ro itself does not block any emails; it only publishes the list of addresses. The decision to reject or filter messages from a listed IP rests entirely with the operators of the email servers who choose to use this particular blacklist.

An IP address can be listed under the following circumstances:

  • If a message is received by an abuse.ro spamtrap from a host that appears suspicious or primarily used for spam, the listing can be immediate.
  • If the sending server is a shared mail server with significant legitimate use, the operator may be given time to resolve the issue before a listing occurs.
  • Operators known to support spam or those with previous listings may be added to the blocklist immediately.
  • Neighboring IP addresses may also be listed if they seem related to a primary listed IP and are likely sources of similar spam.

Who runs abuse.ro Realtime Block List (RBL)?

The blocklist is run by abuse.ro, which describes itself as a collection of classification and reputation databases for public IP addresses and web domains.

How do I get removed and delisted from abuse.ro Realtime Block List (RBL)?

The delisting process from this blacklist is strictly manual. Before you request removal, you must ensure you have taken the necessary steps to stop the source of the spam. The request must come from the owner of the IP block, not the end user.

Before requesting delisting, you should:

  • First, confirm your IP address is actually on the abuse.ro RBL. The operators advise against relying solely on third-party tools and provide instructions for checking directly using nslookup or dig.
  • Identify and resolve the cause of the spam. This may include cleaning infected mailboxes or, if you send newsletters, removing any subscribers who have not explicitly opted-in.
  • Confirm that you or your company is the registered owner of the IP address block. If you are not the owner, you must contact your email or hosting provider to handle the delisting request.

Once the problem is fixed, the IP block owner must send an email to admin [@] abuse.ro with the subject line format: "Delist IP: [your.ip.address.here]". The abuse.ro team may ask for evidence that the spam has stopped before delisting the IP address. Delisting could be delayed if the operator continues to provide services to the spammer.

What's the impact of being listed on abuse.ro Realtime Block List (RBL)?

The impact of being on the abuse.ro Realtime Block List (RBL) is generally considered low. While any listing on a blacklist can cause email delivery problems, this specific list may not be as widely used as other major blocklists. Senders may experience some rejections or filtering, but it is less likely to cause a complete and widespread inability to deliver email.
