+SpamHaus Blocked List - remove IP by going to bottom of "view details"

+Don’t panic!
+The inclusion of your IP address on the Policy Blocklist (PBL) is standard for the vast majority of internet users and is not the result of your actions. Here are some key PBL facts for your understanding:
+	• Being on this list does not mean you won’t be able to send emails.
+	• You do not need to request removal from PBL.
+	• This listing is controlled by your Internet Service Provider (ISP), not Spamhaus.
+	• Your ISP lists ranges of IP addresses that shouldn’t be sending email directly to the internet.
+	• Typically, IPs of broadband or dial-up customers will be included in this list.
+	• This is part of Internet best practices enacted to protect all users.
