European Colorectal Congress 2015: Spamming

On June 26, Professor Doktor Jochen Lange had the bright idea of using the services of to spam to advertise the European Colorectal Congress 2015 that he is organizing. Unfortunately that violates Section 3.3.a of RapidMail’s Allgemeine Geschäftsbedingungen (terms of use).

Even more regrettably, there has been zero response from either Professor Lange, RapidMail, or the Internet service providers involved to an emailed complaint and request for clarification we sent on July 4. There has been more spam on two occasions, however, on July 1 and again today, July 30. Therefore the matter must be made public.

Update Aug 25: RapidMail responded on July 30 to say that they would contact the customer to ask about permission for some random sample addresses. We told them we were looking forward to hearing the results. Nothing since – except for more spam, so we listed

    There was also a response from the spammer themselves on July 30, quoted below in full.

    Dear ?

    This was the scientific programme for a congress addressed to surgeons and gastroenterologists worldwide. During this congress surgeons and gastroenterologists learn how to avoid mistakes during the surgery, how to handle problems and complications.

    This is addressed to surgeons and gastroenterologists as well as scientists in this field in order to support the international scientific exchange.

    Why do you want to forbid something which helps physicians worldwide to improve their job? This helps patients worldwide!

    Furthermore we do not sell any products, it’s just for scientific reasons.

    So please stop sending us emails like that.

    Medkongress AG

    If we were somebody sending out email we would want to know if any of it offended anybody or hit any addresses we didn’t intend it to. But Medkongress AG wants us to shut up. Fair enough; we’ll just publicize the matter and list all their resources.

    Still no further reply from, but more spam advertising the same, so we took all the IP ranges in their SPF record and listed them, and all the domain names in the SPF record and in the spam and listed them too. is now thoroughly considered a spam support ESP.

    Post scriptum:
    The September 17 and 24, 2015 spam runs were from the same old RapidMail range. Towards the end of October, they had moved to a new RapidMail range in The “LAST REMINDER” on Nov 12 was sent again from the old RapidMail range.

    New spam for ECC 2017 just in – from SendinBlue, a French ESP with a strong anti-spam attitude. This will not last long, we suspect.
