Anyone else troubles with abusix.com swisscom 'false positives'?
by Benoit Panizzon 02 Apr '24

02 Apr '24

Hi all Our ISP Email IP Adresses and Domains are, once more, being blacklisted @ Abusix because of, I guess, emails sent to Bluewin Spamtraps. As far as I have figured out, in contact with our customers allegedly sending spam in past cases, those are almost always false positives. There was exactly one case of a business customer indeed sending multiple emails to one or several such bluewin email addresses and did not correctly process the bounces, but then only his dedicated IP was listed, not our customer email domains. But also then, the bluewin addresses he send his newsletters to, he could prove, belonged to his customers. In all other cases, customers sent emails to @bluewin.ch email addresses they knew the owner of. There was even one case where the @bluewin.ch email address in question that was a 'spamtrap' belonged to our customer and he just forwarded his email account with us to his own @bluewin account. It looks like after some 'short' time of inactivity, Swisscom automatically repurposed the bluewin email address of it's customer as 'spamtrap' which of course cause all those issues. Unfortunately I have not yet found anyone @swisscom able to further dig into why this so often causes our email services to get blacklisted or how to avoid this. Abusix.com basically refers to Swisscom as they may not disclose any of those spamtraps and have no information how those bluewin addresses became spamtraps. Can anyone help or knows who @ Swisscom to contact regarding those abusix spamtrap issues?

Historical FTTH availability data: Ready4Order
by Fredy Künzler 02 Feb '24

02 Feb '24

I'm looking for historical Ready4Order data of to visualize the FTTH rollout in Switzerland on a timeline from a scientific perspective. It could become something like this https://ftth.init7.net/ but for example with a time slider. These files are called 999999_35_YYYYMMDD_FTTH_Ready_for_Order_Information.zip and are available for download from the WSG portal to anyone with a BBCS contract of Swisscom. (After login go to Services ==> WSG Information Services ==> FTTx Coverage). However the WSG portal offers only the last five daily snapshots. The file sizes varies from 22Mbyte (2024) to 13Mbyte (2019) and it contains a single .csv file. If you happen to download the file in the recent years, even only occasionally, please let me know off list. Collection of 2023 is almost complete, the one of 2022 mostly ==> the older the better. You may want to ask the person in your company responsible for broadband product management, too. DISCLAIMER: The files must not be made public. They are under NDA which is signed with the BBCS contract. Please don't put it onto a web server w/o .htaccess. Any help would be appreciated. PS. I already asked Swisscom, apparently those files didn't got stored on a regular basis. -- Fredy Künzler Init7 (Switzerland) Ltd. Technoparkstrasse 5 CH-8406 Winterthur https://www.init7.net/

Contact to Ricardo Abuse Desk or Email Admin?
by Benoit Panizzon 30 Jan '24

30 Jan '24

Hi Team Does anyone have means to contact the Ricardo Abuse Desk or Email Admin? There is a possible issue with phishing regarding the CDN provider they use. Ricardo Customer and myself have attempted to bring the issue to their attention, but cases get repeatedly closed with statements like "Ricardo customer service is not in charge of 'technical' issues" Mit freundlichen Grüssen -Benoît Panizzon- -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

Microsoft massive spam outbreak
by Benoit Panizzon 24 Jan '24

24 Jan '24

Hi Users of the SWINOG anti-spam blocklists. At the moment, various Microsoft IP addresses are in a similar state as this one: https://blacklist.imp.ch/entry.php?id=1.0.8.0.0.0.0.0.0.0.0.0.0.0.0.0.2.1.e… Unfortunately, Microsoft has confirmed to me, they use the same bunch of SMTP 'outbound' ip address for customer in similar regions. This is now affecting MSN customer and businesses using Office365. abuse(a)microsoft.com is /dev/null (or mailbox full, depending on their mood) as usual. I'm trying to persuade affected business Office365 customer to escalate this issue within Microsoft Switzerland Management. I also have a contact there to which I repeatedly feed those complaints, without success so far. I am aware, Microsoft Office365 customer service blames this on us 'falsely and for no reason' blocking email from those ip addresses, and when presented with Evidence of what happened, they close the case with 'issue solved' which was never the case.

Any contact to sunrise / chello.at / libertyglobal Postmaster
by Benoît Panizzon 12 Jan '24

12 Jan '24

Hi We have a case of emails reproducible disappearing to one specific sunrise recipient. The recipient is quite sure, he has not activated any filtering rule in his sunrise webmail. He requests us as the ISP of the sender, to investigate the issue 'from the source'. We see in our logs: mx0.sunrise.ch has address 213.46.255.61 is happily accepting the email with 200 OK. No late bounce can be found. Does anyone know, how to contact chello.at for such issue? I have tried the contacts registered @ RIPE for this range. They are either 'not in charge and don't know who is' or do not respond. Sunrise seems not to know how to open a case with chello for such an issue (as last time we faced such an issue). -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

BGP4nerds
by Fredy Künzler 25 Dec '23

25 Dec '23

While I do know that this mailing list is not intended for product announcements, I allow myself to make an exception. In the past years we have been asked so many times "can you do a BGP4 feed via Fiber7, I have my own ASN and IP space" and my answer was always "technically we can but we need to setup a product in our ERP system first and define the implementation process. This will take a while...". To be honest it wasn't our highest priority, though. Of course we forgot meanwhile to whom we were talking and so we are unable to contact people individually. Most people are certainly from this community. Now your prayers have been answered :-) I'm happy to announce that we have now "BGP4nerds" available. Requirement is a new or existing Fiber7 connection - no BBCS (Copper7) or BBCS-F (Hybrid7) based service. We charge CHF 30 per month extra for the BGP service along with a one time fee. This offering is of course strictly limited to non-commercial use and only available to private customers. If you are interested please send a note to sales at init7 dot net with the subject "BGP4nerds" and we'll send you a spec sheet with all the details. Happy Christmas to everyone! -- Fredy Künzler Init7 (Switzerland) Ltd. Technoparkstrasse 5 CH-8406 Winterthur https://www.init7.net/ https://ftth.init7.net/

Hi We are creating an emergency handbook if we would have a critical security incident. Is there someone who can suggest a company which can help to find how the guys hacked the infrastructure and how to fix it? I hope we never have to use it, but be prepared is better Thanks Michael
