Listed on Spamhaus XBL? How to get delisted
xbl.spamhaus.org
What a listing means
The XBL lists IPs of hijacked or infected machines and open proxies sending spam, including the data formerly published as the CBL.
How removal works
Find and clean the compromised device or account behind the IP (check for malware and stolen mail passwords), then request removal on the Spamhaus checker. It relists quickly if the infection is still there.
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.
