I don't understand
what to do about this?
Ref: PBL164253

70.79.164.0/22 is listed on the Policy Block List (PBL)




Outbound Email Policy of The Spamhaus Project for this IP range:

This IP address range has been identified by Spamhaus as not meeting our policy for IP addresses permitted to deliver unauthenticated 'direct-to-mx' email to PBL users.

Important: If you are using any normal email software (such as Outlook, Entourage, Thunderbird, Apple Mail, etc.) and you are being blocked by this Spamhaus PBL listing when you try to send email, the reason is simply that you need to turn on "SMTP Authentication" in your email program settings.

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 70.79.164.0/22 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.
