Anyone have contact with Microsoft network ops?

@kat @pluralistic Once filed, hit me up if you need someone to push from inside the company. Happy to help, especially if I have a name of someone to escalate with (it’s a big company and that’s not a team I work with).

Anyone have contact with Microsoft network ops? They've blackholed my SMTP (204.11.50.134) (which is used by me and half a dozen other people, none of whom send spam), and my admin's on vacation and I don't wanna screw up his time off. This is obviously a false positive though.
@pluralistic One of the larger bills I pay for Internet services is for outgoing SMTP. Basically I pay them to deal with all this shit.

@pluralistic if you find one, please let us know. They blocked one of our IPs and their SNDS system is broken and won't let us add our own IPs so we can't find out why.

@beasts @pluralistic it's only a 3 trillion dollar company, you can't expect them to get basic services right.

@pluralistic
Good luck. I'm sorry I can't help you but I won't be surprised that they blacklisted you **purposely** -

@pluralistic Believe it or not, I have had decent results going through their support channels. This has happened to my mailserver more than once.

Do you know anyone with an @outlook[.]com email address or maybe even a paying O365 customer?
Then just try to send them an email and let them open a ticket about issues RECEIVING mails from you (without mentioning anything that a regular recipient wouldn't know).
That's usually the fastest way to resolve such issues...

@arrrg With all respect, this isn't helpful. I've been self-hosting my mail since the 1990s and the server administration is the former CTO of Wikimedia. We don't have any of these issues, and I'm not in the market for someone telling me that I shouldn't host my own mail.

@beasts@social.mythic-beasts.com @pluralistic@mamot.fr
they seems to have do some change of config recently.
some client on MS have tell us that dkim was broken. It was not but they have raised the bar to 2048bits rsa key for dkim (may be we were lagging behind on that).
we have configured postfix to "talk" slowly to their smtp server, but we have been temporary banned for sending to much mails to them...
such pain, if only they were'nt 1/4 of our mails destinations...

@beasts Same here. I suspect their last mail admin died some time in the last century and nobody noticed yet.

@pluralistic @kat Of course! Hopefully it helps.

@pluralistic @Aaron @kat It would also be good if independent mail server operators file complaints at https://competition-policy.ec.europa.eu/antitrust-and-cartels/procedures/complaints_en so this anti-competitive behavior can be ended for once and for all.

@pluralistic It's a rite of passage. You haven't run a proper mailserver if you haven't been blocked by Microsoft mailservers at least once in your life.

@pluralistic Looks like a mitigation should resolve the issue in the next 24-48 hours. Hopefully sooner.

I'm my companies Office 365 admin. If you'd like, I'll send you my email address and you can email me. And then when it's blocked I can report it as a mistake. I don't know if one report will be enough but it can't hurt.
