What it is

The list, in plain terms.

UCEPROTECT Level 1 (the DNS zone dnsbl-1.uceprotect.net) is the most conservative of the three blocklists run by the UCEPROTECT-Network. It lists individual sending IP addresses only, one /32 at a time — not netblocks or whole providers, which are the job of Level 2 and Level 3.

An IP lands on Level 1 automatically when it hits one of UCEPROTECT's spamtraps, or through a manual listing by a member of the network. Because it targets single IPs rather than ranges, receivers who use it treat it as a comparatively low false-positive list.

Level 1 is consulted by some receivers but is far from universal, and the operator's higher levels — Level 2 by netblock and Level 3 by ASN — are widely regarded as aggressive. If your mail is bouncing on UCEPROTECT, confirm which level flagged you first: an L1 listing is a single IP you can resolve yourself, whereas L2 and L3 are not in your hands.

Why you get listed

What a listing on UCEPROTECT Level 1 means.

Spamtrap hits (automatic) Your IP delivered mail to one of UCEPROTECT's spamtraps. How many hits are needed varies, but 50 or more from a single IP is always treated as a spammer or a compromised machine.

SPF or SRS abuse (automatic) Forwarding mail that the sender domain's SPF record forbids, or falsifying senders with SRS while the sender domain has no SPF set, will list the IP.

Attacks on their infrastructure (automatic) Port scans, probes or other attacks against UCEPROTECT servers cause a Level 1 listing.

Manual listing Any UCEPROTECT-Orga member may list an IP that delivered at least one spam email, is under the control of a known spammer or supporter, or acted fraudulently against the network. Missing, generic or mismatched reverse DNS raises the risk of being listed on a single incident.

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 and the level. Query your IP at the UCEPROTECT lookup and make sure it is Level 1 (dnsbl-1), not a Level 2 netblock or Level 3 ASN listing. Only a Level 1 single-IP listing is something you can clear on your own.
2 Stop the spamtrap hits. Find and stop whatever is sending: a compromised account, a malware-infected host, an open relay or proxy, or forwarding that breaks a sender's SPF. Give the IP valid, matching reverse DNS. The listing will not clear — and will return — while abuse continues.
3 Wait for free automatic removal. You do not need to request anything. A Level 1 listing expires automatically seven days after the last spam email from your IP hits their spamtraps. Every fresh hit resets the seven-day clock, so the cause must be genuinely gone.
4 Pay for immediate removal only if you cannot wait. UCEPROTECT offers an optional paid express delisting, charged per IP and paid by card through Stripe, applied manually once payment is confirmed. It is genuinely optional — the free route always exists — and the IP can be relisted if abuse recurs.
5 Re-check before resuming. Query the IP again to confirm dnsbl-1 no longer returns a listing, then ramp your sending back up gradually rather than all at once.

The official route

Removal happens on UCEPROTECT Level 1's own tool — never through a paid service.

How long it takes

Free removal is automatic: a Level 1 listing expires seven days after the last spamtrap hit. Any new hit restarts the seven-day countdown, so the abuse must fully stop for the clock to run out. The optional paid express delisting is applied manually once payment clears, but an IP can be relisted if abuse resumes.

Common questions

About UCEPROTECT Level 1, specifically.

How do I get off UCEPROTECT Level 1? Stop your IP hitting their spamtraps and the listing expires on its own seven days after the last hit. There is nothing to submit for the free route. If you cannot wait, the operator sells an optional per-IP express delisting.

Is UCEPROTECT removal free? Yes. Automatic removal seven days after the last spamtrap hit costs nothing and needs no request. UCEPROTECT itself also sells an optional paid immediate removal, but you never have to pay. Any third-party service charging to remove you from L1 adds nothing you cannot get free by waiting.

How long does a Level 1 listing last? Seven days from the last spam email that reached their spamtraps. Because each new hit resets the clock, an IP that keeps sending never clears — the seven days only start once the abuse has stopped completely.

Why is my IP on Level 1 when I never sent spam? Common causes are a compromised account or device, an open relay or proxy, or forwarding that breaks a sender's SPF record. Missing or generic reverse DNS can make a single incident enough to list you. Check your outbound mail logs around the time of the listing.

What is the difference between UCEPROTECT Level 1, 2 and 3? Level 1 lists single IPs that you can fix yourself. Level 2 lists whole netblocks and Level 3 lists entire ASNs, escalating when abuse from a network persists — those you cannot delist alone, and your provider has to act. Confirm your level before doing anything.

Should I pay to be delisted from UCEPROTECT? Only if waiting seven days is genuinely too costly, and only through UCEPROTECT's own express delisting. Paying does not prevent a relisting while the underlying abuse continues, so fix the cause first either way.
