ACC Consulting Oy endangers the email deliverability of the entire Elisa Oyj customer base

Today, it transpired that Spamhaus.org have created an informational non-blocking listing for the consumer outbound mail servers (195.197.172.0/32) of Elisa plc, aka Helsinki Telephone Co, based on the spam that is being sent out by our old friend Acc Consulting Oy.

Based on the events surrounding a similar issue with the generic customer outbound mail service of Anvia plc (see SBL221497), it appears that such issues have a tendency to escalate into actual blocking listings if left unattended.

Can Elisa plc afford to have the deliverability of every single customer of theirs compromised because of one abusive customer? Inquiring minds want to know.

Update: I hadn’t noticed Helsingin Sanomat, the prime Finnish daily newspaper, have written about Acc’s spam back in the end of March. 🙂

Update 20140514: Updated the text with the target of the informational listing. Elisa seem to have gotten off their bums and removed the problem, and hence the listing has been removed. That is a welcome development. I hope it is genuine.

  1. On May 20-21, the debt collection arm of Acc Consulting Oy, Justin Perintä Oy, managed to use the same servers for spamming some more. They seem to have done this via the use of prepaid cell broadband:


    Received: from gw0X.mail.saunalahti.fi (gw0X.mail.saunalahti.fi [195.197.172.x])
    by x (Postfix) with ESMTP id x
    for <x>; Wed, 21 May 2014 hh:mm:ss +0300 (EEST)
    Received: from SATC660D11K-PC (85-76-67-172-nat.elisa-mobile.fi [85.76.67.172])
    by gw0X.mail.saunalahti.fi (Postfix) with SMTP id x
    for <x>; Wed, 21 May 2014 hh:mm:ss +0300 (EEST)

    …which is what I predicted would happen.
