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 It's a rite of passage. You haven't run a real mailserver if you haven't been blocked by Microsoft mailservers at least once.
@pluralistic you probably just need a couple of dns records to prove you are who you say you are (smtp anyways).
@pluralistic and for what's it's worth, it's not worth it to host your own smtp server - usually. it's a major pain in the ass.
@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.
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...
@pluralistic Believe it or not, I have had decent results going through their support channels. This has happened to my mailserver more than once.
@pluralistic
Good luck. I'm sorry I can't help you but I won't be surprised that they blacklisted you **purposely**
@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.
@pluralistic my condolences are all i can offer
@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 Sir, I do not wish to frighten or alarm you, but dealing with Microsoft with regard to email issues is akin to performing an auto appendectomy with nothing but LSD and Absinthe as an anesthetic.
I wish you luck. Moreso, I truly hope you retain your sanity and composure in the face of the Lovecraftian horrors that lie before you.

@pluralistic go to olcsupport.office.com and log a ticket. They do resolve things. It normally takes two iterations. They say there is nothing wrong with your IP, then if you think there still is, send them error messages. But it does get fixed.
Logs and error messages help.
