What is UCEPROTECT Level 1?
UCEPROTECT Level 1 lists individual IP addresses that delivered mail to the project's spam traps or violated its sending policies. It is fully automated: no human review on the way in, and a fixed rule on the way out. An IP drops off the list exactly seven days after its last recorded incident.
UCEPROTECT is also known for its aggressive escalation tiers (Level 2 lists whole ranges, Level 3 whole providers) and for offering paid "express delisting" through its whitelisted.org service. That combination has made the project controversial among mail operators, and most large receivers weight its data lightly or ignore it.

How serious is a UCEPROTECT Level 1 listing?
Modest. Some smaller mail servers and appliance configurations query Level 1 as a blocking or scoring signal, so you may see occasional rejections referencing uceprotect.net. Major mailbox providers do not block on it. It is worth resolving, but calmly: the trap hit that caused it often points at a genuine list-hygiene problem, and that underlying problem is the part that hurts you at bigger providers.
Why your IP got listed
Mail to UCEPROTECT spam traps
Trap addresses live inside old, purchased and scraped lists. Hitting one means your list contains addresses no legitimate opt-in process would have produced.
A compromised account or relay
Spam pushed through your server by an intruder lands in traps just the same.
Aggressive retrying or policy violations
UCEPROTECT also lists for behavior it deems abusive at the SMTP level, such as hammering its servers after rejections.
Why there is no removal form, and how the listing clears
automatic expiry, or paid expedited delisting. There is no form and nobody to write to; the list rebuilds from its own observations, and an entry ages out on its own (7 consecutive spam-free days) once the behavior it recorded stops.

Check the listing details
The lookup at uceprotect.net shows the listing, its expiry countdown and the incident basis. Note the date of the last hit: that plus seven days is your automatic release date.
- 2
Stop the source of the trap hits
Purge stale and acquired segments from your lists, verify no account or form is compromised, and pause bulk sending from the IP if you can. Every new hit resets the seven-day clock.
- 3
Let the listing expire on its own
Seven days of clean behavior and you are out, free. This is the recommended path in almost every case.

Pay only in a genuine business emergency
UCEPROTECT's whitelisted.org offers immediate delisting for a fee (in Swiss francs, per IP). It works, but it neither fixes your list problem nor prevents relisting, and rewarding pay-to-delist economics is why many operators distrust the project. If a critical receiver is blocking you on Level 1 and you cannot wait a week, it exists; otherwise skip it.

How long removal takes
Automatic removal exactly 7 days after the last trap hit or policy incident. Paid express delisting via whitelisted.org is near-immediate but costs money per IP and does nothing about the cause. Continued hits extend the listing indefinitely, seven days at a time.
Frequently asked questions
How long does a UCEPROTECT Level 1 listing last?
Exactly seven days after the last incident, with removal fully automatic and free. Each new trap hit resets the clock, so a listing that never expires means your mail stream is still producing hits.
Should I pay for UCEPROTECT express delisting?
Rarely. The paid route via whitelisted.org removes the entry immediately but is per-IP, does not prevent relisting, and addresses a list that most large providers barely weight. Reserve it for a concrete emergency where a business-critical receiver blocks on Level 1 and a week's wait is unaffordable.
Do Gmail or Microsoft use UCEPROTECT?
There is no evidence major mailbox providers block on UCEPROTECT data, and its escalation tiers are widely criticised precisely because they flag innocent bystanders. Its practical footprint is smaller mail servers and some appliance default configs.
