Listed on UCEPROTECT: should you worry, and how to delist

A UCEPROTECT listing looks alarming but rarely affects delivery. UCEPROTECT runs three lists, and the higher two list entire allocations or ASNs — not your specific behaviour.

What it means

Level 1 lists a single IP that actually sent spam. Level 2 lists the provider allocation the IP sits in; Level 3 lists the whole ASN. Levels 2 and 3 can list you purely because a neighbour misbehaved.

Why it happens

UCEPROTECT is widely regarded as low-value because of aggressive range listings and a paid express-delisting offer. Most major mailbox providers do not use Levels 2/3 to reject mail.

Diagnose it

Run the blocklist check to see the full picture. If only UCEPROTECT Level 2/3 lists you — and reputable lists like Spamhaus and Barracuda are clean — this is almost certainly not the cause of any real delivery problem.

Fix it

1. Do not pay for express delisting — it rewards the model and Level 2/3 will re-list.

2. If only Level 2/3 lists you, treat it as your hosting provider’s range issue, not yours; it is usually safe to ignore.

3. If Level 1 lists you, find and stop the spam source on that specific IP, then use the free delisting.

4. Focus remediation on Spamhaus, Barracuda and provider blocks, which actually gate delivery.
