Why IPs and domains typically get listed
Most listings on composite lists like this trace back to spam complaints from recipients.
A compromised mail account or server sending unsolicited mail is a common cause.
Spam traps, which are addresses that never opt in and only catch spam, can also trigger a listing.
Missing or broken sender authentication, such as SPF or DKIM, makes a server look more suspicious.
Poor list hygiene, like mailing stale or purchased contact lists, drives complaint rates up too.
Because this zone also works as a URIBL, a listed domain can get you flagged too.
That happens even if your own mail server is clean.
That happens when spammers link to your domain, or use a URL shortener that redirects to it, inside their messages.
How to check if you're listed
Start with a direct DNS lookup against bl.fmb.la for your sending IP or domain.
Any DNSBL lookup tool that supports custom zones can run this query for you.
,Fmb.la's own site shows Level 1 Listings at 127.0.0.2, Level 2 Listings at 127.0.1.2, and Level 3 Listings at 127.0.2.2,, each with its own lookup view.
Check both your server's IP and any domains your emails link to, since either can trigger a listing here.

How to get removed
Confirm exactly what's listed first, an IP, a domain, or both, using the lookup above.
,To delist an IP address, the FCrDNS must be confirmed and you must have control over the FCrDNS domain.,
That means your IP's reverse DNS record and that domain's forward DNS record need to match.
You also need control over the domain used in that FCrDNS record to request delisting.
Fix whatever caused the listing before requesting removal, or the IP is likely to get relisted.
That could mean closing an open relay, securing a compromised account, or fixing broken authentication records.
Next, go to the fmb.la site and sign in to access its delisting process.
The portal has used Google sign-in for access in the past, so have that account ready.
Delisting requests on this zone have been handled by adding a TXT record to prove domain control.
If a domain is listed instead of an IP, the same domain-control proof generally applies.
Submit the request once your TXT record is in place and your DNS has propagated.
How long it typically takes
Fmb.la does not publish a fixed turnaround time for delisting requests.
Composite lists built from multiple reports often review requests faster than large commercial blacklists.
Expect the DNS propagation step alone to take up to a few hours before you can submit.
After that, processing time varies and isn't something you can reliably predict in advance.
Re-checking the lookup page a day or two after submitting is a reasonable first checkpoint.
FAQ
How do I check if my IP or domain is on fmb.la uribl?
Run a DNS lookup against bl.fmb.la using your IP address or domain name. You can do this with most DNSBL lookup tools that accept custom zones. Fmb.la's own site also shows current Level 1, Level 2, and Level 3 listings. Check both your sending IP and any domains linked in your email content.
How do I remove my IP from fmb.la uribl?
First confirm what's listed, since this zone covers both IPs and domains. For an IP, fmb.la requires FCrDNS to be set up and confirmed before it will process delisting. You'll need control over the domain tied to that reverse DNS record. Fix the underlying spam issue, then submit your request through the fmb.la site.
What is FCrDNS and why does fmb.la require it?
FCrDNS stands for forward-confirmed reverse DNS, a check that your IP's reverse DNS matches a real, controlled domain. Fmb.la uses it to confirm you control the mail server tied to the listed IP. Without a matching FCrDNS setup, the site won't process an IP delisting request. Setting up correct reverse DNS is also good mail server practice generally.
Is there a fee to get delisted from fmb.la?
Fmb.la describes itself as a free to use blocklist for email classification. No delisting fee is documented on the operator's own site. If any limits or paid tiers exist, they are not publicly detailed. Treat delisting as free unless the site's process tells you otherwise during your request.
Why would my domain get listed if my server was never compromised?
This zone also works as a URIBL, meaning it tracks domains and links found inside spam messages. Spammers sometimes link to or spoof legitimate domains without ever touching that domain's own server. A URL shortener pointing to your domain can trigger the same kind of listing. In that case, the fix is proving domain control rather than cleaning a mail server.
