SPEWS Memorial Day

Every August 30th the APEWS.org website changes it's home page to show the following;

 **************************************

Today our website and our mail-servers are not available, because it is 30 August - SPEWS MEMORIAL DAY

Our beloved SPEWS operator got hit by a truck and died 30 August 2006. One of his dreams was to make the world a spam free place.
As long as spam exists we therefore recommend all of you to shutdown all mail-servers at every 30. August for 24 hours.
Be creative to make today a black day for all spammers and spam supporters and a day without mail and spam.
It is just one day in the year so it will not hurt you nor your company, but it will set a widely visible sign if enough people do so.
Our blacklists are online, but we will not display reasons for listings nor do any removals by today.
We will be back by tomorrow. APEWS - Anonymous Postmasters Early Warning System.

 **************************************

The man behind the former blacklist known as SPEWS was visionary in that he recognized that playing with dynamic listings was mot a solution, just prolonging the problem and in fact permitting both spammers and anti-spammers to continue to profit from the problem at the expenses of the general public internet users.

Instead he designed a fixed listing system that prevented the internet service providers (ISP) from recycling their IP space for profit, listing them as having a bad reputation. The SPEWS blacklist database was known to be fairly aggressive with the ISPs that ignored the spam problem whilst making money from it.

From what we know, the founder of SPEWS was not only an experienced driver but had additional training possibly as a driving instructor. He also liked to drive one of the safest cars manufactured yet, despite this, whilst driving his usual cross-country route between home and office, a truck appeared and there was a crash that left the SPEWS founder dead. That was August 30th 2006. Was there foul play?

We think that if the SPEWS founder was still alive today, he would be pleased with the progress that APEWS.org has made using his ideology and advancing it further to cover all ISPs and IPv4 space.

The delivering server is using an incorrect HELO/EHLO, it should be a FQDN (fully qualified domain name) and to do that you need to contact your ISP, Windstream, and tell them what FQDN you want them to write in their DNS server for a PTR record. Windstream are using generic PTR records which are not satisfactory for email servers, yours is showing as;
h66.36.39.162.static.ip.windstream.net
That alone will cause your emails to fail reverse DNS lookups that many email servers perform automatically in realtime.
Using Windstream IP space probably isn't doing you any favors either. If they won't do that DNS entry for you, you'll have to change ISP or accept a poor delivery rate.
The person that did the setup of your email server does not know enough to do the job, we suggest you contact a professional who should know about things like EHLO/HELO configuration and SMTP per RFCs.

No evidence of Apews listing causing this email delivery failure

Herewith is the header of the bounced email. IP is not blacklisted in other anti-spam portals except with APEWS though it's still a July 07, 2007 record.

This looks like your connection to the server was authenticated correctly and that the email delivered correctly too. It seems to have failed on possibly content of the email or other parameters that were tested for during/after receipt of the email. I suggest that you contact the server administrator. There is no mention of a failure due to an Apews.org listing.
