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 Do you have regular contact with people using outlook or ms365 accounts? MS blocks your ip when there were too less mails were sent in the past.
Do you have an exact error message?
@pluralistic I would not be surprised if your problem is related to the last line:
```
NetRange: 204.11.50.128 - 204.11.50.143
…
NetName: PRIORITYCOLO-204-11-50-128
Organization: Boing Boing (BB-50)
Comment: Note: We run a TOR exit relay on 204.11.50.131, The node at this IP address is very likely protected by DMCA "Safe Harbor" provisions as a result.

getting a MSFT contact to fix mail….. sorry, but can only wish you good luck :(
@jeroen It's fixed, thanks.
@pluralistic Then, you had luck ;)
@pluralistic We definitely need a solution to this.. Microsoft & Google effectively control what e-mail gets sent and what does not today.
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.
@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.
@hzulla @pluralistic a.k.a. "vibe blocking" ;)
@stealthradek
And if your NTP servers are down then you're doing "vibe clocking"
@hzulla @pluralistic
@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.
