How do I find out if a server/ISP is on your Spam blocklist?
As described in our Spam FAQ, AzNET uses both third party Spam blocklists (also known as "RBL"s, or Realtime Block Lists), as well as private Spam filters that are set up on a case-by-case basis.
If you'd like to check and see if a mail server or ISP is on one of the third-party Spam blocklists we subscribe to, enter the domain name (i.e. the part after the "@" symbol in an email address, such as "hotmail.com", "freestuff.com", etc) in the box below and click "Submit":
