Public notice to Web Werks Pvt Ltd [EnterpriseDCTAC #CAV-139-41061]

We have already once commented in public on this website (see earlier article) about the difficulty of communicating with you when you write in from a ticket system. This is just a heads-up; we have responded to you. If you don’t see our response, it’s not our fault. If you expect us to respond in your ticket system rather than in e-mail, don’t hold your breath.

Mar  5 11:31:39 x postfix/smtp[21423]: 89B9413E055: to=[email protected],[]:25, delay=203, delays=0.05/0.04/200/3.1, dsn=2.0.0, status=sent (250 OK id=1j9oj3-0000Gh-CZ)

And as for the issue itself:

  1. Our services are not used by Yahoo, Hotmail and Gmail.
  2. Your RFC 5322 noncompliance issues are not related to Scientific Spam DNSBL listings and cannot be fixed by Scientific Spam.
  3. Get rid of OMICS.

Happy Birthday, Scientific Spam

It is already six years and a day since we started operations.

Usage has gone ~25% down on the IP list, with 1.7 billion queries recorded in 2019 (over 2.3 in 2018). The decline is even more marked on the right-hand side list, with 1.4B in 2019 compared to over 3B in 2018.

As always, thank you to everybody who is querying the data. If you have any suggestions, the usual email address is listening.

Public notice to MailKitchen

We replied to you on October 24, 2019, and again on Nov 5 (if only to indicate that we had already replied). You keep sending in new messages that don’t indicate you’ve seen any reply from us. We keep deleting the new messages. If you want to have a conversation, you need to have a conversation, and that means reading our replies and responding to them.

You write to us from a ticket system, we respond to you, and then you never respond back to us, eventually closing the ticket as nothing further has been heard from “us” on “our issue”.

Hey, that’s okay. We don’t mind your issue with us staying unresolved. But as far as we remember, you started the conversation…

Marketo, an Adobe company

Back in January, a representative of the ESP Marketo attempted to start a delisting discussion by leaving a comment on one of the posts on this website. We declined to discuss the matter in public as we always do.

So, knowing that Marketo is a serious ESP and is generally able to carry out a conversation related to abuse, we sent an email to abuse @ marketo . com quoting the content of the website comment we declined to publish and responding to the points in it, asking for a response.

Nothing until today – when their ticket tracking system was kind enough to inform us of the fact that Marketo Delivery Case #01266633 had been closed.

Five months of nothing and then an auto-ack. Good work.

Scientific Spam 5 years

Scientific Spam IP BL query rates development over the past 5 years

During 2018, we saw a modest 15% growth on the list query rates from 2017 on the IP list. The domain name list more than doubled its queries from 1.5B to over 3 billion over the same period.

As of writing this, there are nearly 8,000 IP listings, of which 2600 are for /24’s and the rest for single IPs. Nearly 4,900 domain names are listed.

Thank you to all who are querying this data. You are the difference between this being just a random blog on the internets and an actual useful resource.

Predatory publishers are The Borg

This just in on the removals email address:

Received: from [] (port=46330 helo=HEIGHPUBS)

(envelope-from [email protected])

In other news, Peertechz are using IP ranges to send their mail that had already been listed on our list as belonging exclusively to OMICS. In addition, they have named their box HEIGHPUBS, which is a hallmark of “Heighten Science”.

We rest our case.

Remove Boxtrapper and all other Challenge/Response spam-o-matons


This is something we have discussed before…

If we listed you because of the backscatter, and you write in to ask for it to be removed, and we receive a C/R so that our reply would be delivered to you…

That’s just wrong.

We won’t click on it. You won’t receive our reply, and the conversation will never proceed, and you will not be delisted. But that’s OK – the support conversation we just attempted to have with you actually proved the validity of our listing once again.

Challenge/response is spam. Stop it.
