You might like to share the IP(s) that you are concerned with to the
list. We are seeing more and more, a trend where email providers are
getting more aggressive with hosting providers known for allowing
spammers to set up shop.
Hosting providers are going to have to start improving the ways they
monitor their own networks, and the types of customers they are allowing
to set up shop, or you can expect MORE providers just 'blocking'
providers until they clean up their email practices.
Also, it is incumbent on large hosting providers to keep up accurate
SWIP and/or rwhois records when delegating IP(s) and IP ranges to
potential customers. (Per ARIN/RIPE guidelines on these matters)
And especially with recent rulings, and CASL legislation etc getting
more aggressive with penalties, it won't surprise me when the providers
are seen to be 'partly' "responsible" for the activities of their
customers and their networks.
(Frankly, always have been surprised that especially in the US, with
their more aggressive legal system, that actions haven't been taken
against some of the well known 'havens' for spammers.)
I always remember the one hosting company I talked to, about monitoring
their networks, and his statement that they don't monitor their
customers, because "..they can't be responsible for what they don't know.."

Hello,
We're currently having some major issues with our IPs being blacklisted
by Microsoft. I'm signed up for the SNDS and a huge amount of our IPs
are "blocked due to user complaints or other evidence of spamming".
It's fairly easy to have the IPs delisted by filling out the "Sender
Information for Outlook.com Delivery" form that Microsoft provides.
However, that only allows up to a /24 to be delisted at a time, which
means it is going to take a very long time to delist all of our ranges.
Also, that doesn't actually address the underlying issue. Obviously spam
isn't being sent from all of those IPs, but there has to be some reason
Microsoft is listing them all.
Is this something anybody here has experienced? Better yet, is there
somebody from Microsoft who could have a quick look at this and give me
some insight into the underlying issue? I've been attempting to contact
Microsoft for a while now and only ever get canned responses (if at all).
Any tips or help would be greatly appreciated, thanks.
Kind regards
