Removing a mail server from the Spamhaus PBL
Removing a mail server from the Spamhaus PBL
How to check if your IP is listed.
Spamhaus assists Internet service providers with preventing unsolicited email (spam) from passing through their mail servers. One of the tools Spamhaus employs is a “Policy Block List” (PBL) that lists addresses that get assigned to customers of dial-up, broadband, and hosting service providers. Those addresses are then blocked by default and have to be manually removed from the list when someone has a legitimate need to use one of those addresses to run a mail server (as many Slicehost customers do). It is therefore likely that a new slice, or one that hasn’t been used as a mail server before, will be on the Spamhaus PBL.
Being on the PBL doesn’t mean your address is blocked for spamming. The list is only there as a precaution against potential abuse. Spamhaus applies this policy to any IP addresses that could change hands from one customer to another. Their goal is to prevent computers that should not be sending email directly from being able to do so if they are compromised in some way.
