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@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.
Mit freundlichen Grüssen

I see, here you can see a more detailed feedback (mostly from users though):
https://answers.microsoft.com/en-us/outlook_com/forum/all/microsoft-outlook-...
A customer of mine was hit with his problem, and I suggested work-arounds and to show the customer customer's the extent of the problem.
The obvious solution would be that everyone gets a Microsoft hosted mail service and drops independant service providers :)
NB: apart from the joke, it gets every day more complicated to manage an independant SMTP provider, notably due to a very feelable concentration of individuals, but also enterprises within one or two GAFAMs: unfortunately we no longer live in an Internet world where we can say "Microsoft is irrelevant": most universities and enterprises seem to have been lurred there.
Hi All,
Honestly... if Microsoft is the Solution I'd rather keep my problem.
Jokes aside... They are simply trying to play the "we are bigger than you"-game - which isn't really working. Never has.
