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

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 ______________________________________________________
