delist@ is very much monitored, but December saw an incredible increase in
abusive traffic thru our system, and responses ... have been delayed.
Aloha,

Subject: [EXTERNAL] [mailop] blocked by microsoft -- support procedure?
Hi,
I'm not generally involved in our support issues, but a coworker at
my work (Linode) reached out to me about what looks to be a new problem
involving hosting customers being blocked by by Microsoft. We have
150-200 new support tickets about this, starting on December 21, 2021.
Our support goes back and forth with the customers and tries to help,
typically 4 responses, but up to 48, per ticket, and both support and
customers are growing increasingly frustrated.
Customers and our support team have been reaching out to
del...@messaging.microsoft.com, but are concluding this is non-monitored.
Linode doesn't provide any e-mail services for the customers, so all
these involve different customer-allocated IPs and different hosting
customers. While the ones I'm spot checking, looking at these tickets,
have DNS, SPF, and other mechanisms set up appropriately, of course
the situation varies. At least some of these customers and/or our support
has confirmed their Linode IPs are not listed on any public DNSBLS they
can find.
Linode has by default blocked all outbound SMTP for all accounts starting
November 2019, until customers have met certain criteria. I have not
become aware of any recent large or not-promptly addressed spamming
problems, nor seen recent mention of spammers from Linode IP space on
here or other e-mail hosting related lists since I started here in
January, 2020.
I saw the December thread on this list from a listmember who is (or was?)
Linode hosted, and ran into this MS blocking Linode trouble.
Here's an example from one ticket, however I'm more looking for whether
there is anything I can do to facilitate improving this overall, then
starting trying to intervene about (many!) specific tickets and IPs. I
would be happy to help with more details off-list, if so requested. I
also could relay suggestions or procedural instructions to our support
group.
