Ascams Super Block Scoring List
The Ascams Super Block Scoring List is an IP blacklist (or blocklist) using abuse scores. Senders must resolve issues and lower scores for removal.
Updated on 18 Jun 2026: We updated this guide to clarify Superblock scoring, delisting requirements, and when administrators should avoid using it as a hard reject list.

The Ascams Super Block Scoring List is an IP-based scoring RBL and blocklist (or blacklist). It uses the "Everyone Leaks" idea: any internet server can send abuse at some point. An IP resource is listed when its Ascams reputation score crosses a threshold tied to spam, phishing, scams, malware, unsolicited bounces, or other abuse.
The score is dynamic. Ascams says it changes based on abuse type and frequency, the IP neighborhood, abuse history, bounce behavior, and how the resource manager accepts and acts on emailed abuse complaints. Ascams states Superblock has no false positives because each listing is tied to abuse data from the resource. The score decides which of the 12 Ascams data lists the IP appears on.
Who runs Ascams Super Block Scoring List?
The Ascams blocklist is managed by an individual named Del. Ascams maintains reputation scores for IP resources and says it does not use paid sender score services, whitelists, or club memberships to exempt senders. It evaluates IP resources based on long-term reputation and operator response to abuse, regardless of the size of the organization operating them.
What's the impact of being listed on Ascams Super Block Scoring List?
The impact of being listed on the Ascams Super Block Scoring List is usually low compared with major mailbox-provider filtering. Large mailbox providers like Gmail and Microsoft do not publicly list it as a core source. However, a listing indicates an email sending issue, compromised host, poor abuse handling, or risky IP history. Some administrators use this blacklist as an RBL score input, so a listing can contribute to spam placement or delivery failures at certain receiving systems.
How should mail administrators use Superblock?
Ascams describes superblock.ascams.com as a score RBL, not a drop DNSBL. That distinction matters: a drop DNSBL result is used to reject a connection immediately, while Superblock is designed to add a numeric reputation score to the receiving server's spam decision.
Using Superblock as a hard reject list risks refusing legitimate mail, especially when a sender mixes transactional, personal, bulk, and abusive traffic on the same IP range. Administrators who use it should set a local score threshold and combine the result with their existing mail server policy rather than treating every listing as an automatic block.
How do I get removed and delisted from Ascams Super Block Scoring List?
The delisting process from the Ascams blacklist depends on your IP's score and whether the abuse has stopped for the reputation period. In many cases, removal is automatic after the source of the abuse is fixed. The first step is to secure the host, account, application, or customer that caused spam or malicious traffic, then confirm the IP is no longer leaking abuse.
Once the problem is resolved, request removal through their portal. The process requires creating an account, confirming the login link by email, entering the IPv4 address, reviewing the displayed IP score, and using the 'Remove' button when the portal allows it. If successful, the IP is delisted within three hours. You start the process on the Ascams login page.
If the IP score is too high, removal becomes a manual process. Ascams weighs listing age, abuse history, neighborhood reputation, unsolicited bounce behavior, the operator's response to complaints, and whether the person requesting removal is the listed abuse contact. Before requesting removal from this blocklist, Ascams suggests following a few guidelines:
- Stop the abuse and confirm that spam, phishing, malware, unsolicited bounces, or other malicious traffic has stopped.
- Check whether the listing is less than 12 months old, because older listings add reputation weight and signal unresolved abuse handling.
- Verify that reverse DNS has a single PTR name, that the forward DNS matches, and that the name belongs to a real mail server.
- Publish an abuse contact email address that accepts emailed complaints and responds according to your AUP or terms of service.
- Confirm port 25 is open for the mail server, operational, and not an open relay.
- Review other blacklist and blocklist listings first, because Ascams expects the IP to be cleaned up before removal.
- Review the IP resource history and neighborhood. If you recently acquired a dirty range, the service provider or resource holder often needs to handle the request.
In difficult cases, the resource owner or service provider needs to get involved. If the IP is removed and then relisted for the same issue, its score increases, making future delisting harder. For senders using authenticated email, Suped's DMARC reporting can help separate legitimate domain traffic from abuse or misconfigured sources before another blocklist listing appears.
