ASPEWS

The simplest way to check against the ASPEWS list is to query using an IP address either out of an email header or one that corresponds to a webpage URL domain or DNS server domain.

Put the “dotted quad” (aaa.bbb.ccc.ddd) into the “Lookup IP Address” box at the top of this page, hit return and a check against the ASPEWS list will be performed.

The results can be:

• This was NOT found in ASPEWS, which means ASPEWS has not seen spam or spam services coming from this area of the Internet. It does not mean there may not be a spammer there, just that it has not been ASPEWS listed. You may also wish to try the IP address at the Spamcop, Spamhaus or MAPS websites. There are utilities provided at OpenRBL, Moensted.dk, SORBS and at SamSpade that will allow you to test against multiple blocklists at once.
• This IP address was found in ASPEWS, which means ASPEWS has seen spam or spam services in this area of the Internet. The entries in the list come from the knowledge and experience of the people who set up and use the ASPEWS lists for their own filtering and blocking purposes.

What you do with the result of a lookup is up to you. What you are seeing is just a recommendation by ASPEWS that, to help prevent spam, you may wish to filter or block IP address ranges that come up positive in the test. People trying to email from these IP addresses to systems using SPEWS will normally see a “bounce message” with a link to our “Why was I referred to this website?” page.

Another use people put the ASPEWS check to is verifying that a host or network they plan to set up on is not spamming or supporting spammers in any way. Not being listed in ASPEWS is not a guarantee of any kind to this, but being listed is not a good sign.
