The Spamhaus PBL

I don't understand
what to do about this?
Ref: PBL251585 is listed on the Policy Block List (PBL)

Outbound Email Policy of Sky Broadband for this IP range:

It is the policy of Sky Broadband that email sent from this IP address should be sent out only via the officially supported Sky Email outbound SMTP service, or via any authenticated third party outbound SMTP service of which a Sky Broadband user is a customer.

For Sky Broadband customers using the officially supported Sky Email outbound SMTP service, configuration information for most email programs in common use appears in the Sky Email section of the Sky Help Centre portal.

Sky Broadband users using third party outbound SMTP services who experience mail blocking issues due to this listing should take this up with the support department for the third party outbound SMTP service concerned. The Spamhaus Project recommend that mail service operators should not use the Spamhaus PBL list to block outbound mail that their own users are sending however unfortunately, some do.

Questions about this policy should be directed to

Removal Procedure

If you are not using normal email software but instead are running a mail server and you are the owner of a Static IP address in the range and you have a legitimate reason for operating a mail server on this IP, you can automatically remove (suppress) your static IP address from the PBL database.

About The PBL

The Spamhaus Policy Block List ("PBL") is an international anti-spam system maintained by The Spamhaus Project in conjunction with Internet Service Providers and is used by Internet networks to enforce inbound email policies. The PBL database lists end-user IP address ranges which should not be delivering unauthenticated email to any mail server except those provided for specifically for that customer's use. The PBL lists only IP addresses (not domains or email addresses).

For full information on how the PBL operates please see the PBL Home page and the PBL Frequently Asked Questions.
