Why IPs typically get listed
Fabel lists an IP after it sends spam into their network or to fabel.dk members. This is the same general trigger used by most spam-source blacklists.
Common underlying causes include a compromised mail account, an open relay, or a server sending bulk mail without proper authentication like SPF or DKIM. Spam traps and poor list hygiene can also trigger a listing on lists like this one.
Fabel has a specific wrinkle worth knowing. Someone or something on your network sent them spam. Some network (in particular in South America and Asia) does not maintain very good records in whois, so a large netblock including your IP might have been included in their list.
In plain terms, this means your IP can get swept into a listing even if it never sent anything bad. If your whois abuse contact is wrong or unresponsive, Fabel is more likely to block the wider range instead of just your address.
Shared hosting IPs get hit by this often. Many inexpensive "shared hosting" providers are struggling keeping abuse and spam off their networks. This leads to their IP addresses getting listed as potential spam sources.
How to check if you're listed
Fabel provides its own lookup page for checking a specific IP against the list. You can also query the zone directly over DNS if you run your own lookup tools.
A standard multi-blacklist checker like MXToolbox will also flag a Fabel listing alongside other blacklists. That's a faster first step if you don't yet know which list is causing your bounce.
If your mail server logs show a bounce message mentioning spamsources.fabel.dk, that confirms the listing directly. The bounce text usually includes a link back to the specific listing page for your IP.
How to get removed
Fabel runs a self-service delisting page rather than a manual review team. You can do it yourself on our delisting page.
Start by confirming no mail account or script on your server is still sending spam. If you're on shared hosting, loop in your host first.
Next, check the whois abuse contact listed for your IP address. Fabel says incorrect or unresponsive abuse contacts make a broader netblock listing more likely.
Then visit the Fabel delisting page and submit your request. Recent accounts of the process describe logging in with your email address, entering a verification code sent to your inbox, then submitting your IP along with a short explanation of what you fixed.

Keep the explanation specific. Mention what caused the spam and what you changed, like securing a compromised account or adding SPF and DKIM.
How long it typically takes
Fabel's own FAQ states a fast turnaround for this list. The DNS list will typically update within 20 minutes.
Some third-party guides cite a slightly wider window of 20 to 30 minutes after a successful submission. Either way, this is one of the faster DNSBLs to clear once your request goes through.
If you still see the listing after an hour, double check that your submission actually went through. A failed login or verification step is a common reason requests don't register.
FAQ
How do I run a Fabel Spamsources blacklist check?
Use Fabel's own lookup page and enter your IP address directly. You can also run a multi-blacklist checker like MXToolbox, which checks Fabel alongside dozens of other lists at once. Either method will tell you if your specific IP is currently listed.
How do I remove an IP from Fabel Spamsources?
Fix the underlying spam source first, whether that's a compromised account, an open relay, or missing email authentication. Then submit a delisting request through Fabel's own delisting page with your IP address. Include a short note on what you fixed, since Fabel's process asks for this context.
Does Fabel Spamsources list domains or just IPs?
Fabel only lists IP addresses, never domain names or websites. If your website itself is down or flagged, this blacklist is not the cause. Check your mail server's sending IP instead.
Will my IP get relisted after removal?
Yes, if the spam source that triggered the original listing is still active. Fabel's policy is based on ongoing spam reports, not a one-time penalty. Make sure the account, script, or open relay that caused the listing is actually fixed before you request delisting.
Why is my shared hosting IP on this list?
Shared hosting IPs are often listed because other customers on the same IP sent spam. Fabel notes that budget hosting providers often struggle to keep abuse off their networks. Moving to a dedicated sending IP or a reputable transactional email provider can prevent this from recurring.
