Listed on UCEPROTECT Level 2? How to get delisted
dnsbl-2.uceprotect.net
What a listing means
UCEPROTECT Level 2 escalates to whole allocations when several IPs in the same range are listed at Level 1. You can be listed for your neighbours’ behaviour.
How removal works
Level 2 clears when the Level 1 listings in the range expire. Ask your provider to deal with the abusive neighbours; most large receivers do not use Level 2.
Before you request removal
- Confirm the listing with ProbeKit’s blacklist check and note every list that shows the IP or domain.
- Find the cause: compromised mailbox passwords, malware on a device, an open relay or open proxy, a misbehaving web form, or sending to purchased or stale lists.
- Fix it, and make sure the IP has a proper reverse DNS (PTR) name and that SPF, DKIM and DMARC pass for your mail.
- Use the list operator’s removal process. Requesting removal before fixing the cause usually gets the IP relisted.
- Re-check after a day, and add a blacklist monitor so you hear about the next listing before your users do.
