Ask HN: How do people self host email and maintain deliverability?
3 by smithbob | 3 comments on Hacker News.
I wanted to self host my email and decided to rent a VPS. I made sure the ipv4 address was on no blacklist. My domain uses a good TLD with a long domain history. I set up SPF, DKIM, DMARC, reverse IP DNS, etc. I sent 3 emails to my personal outlook/hotmail accounts, all of which went to spam. 1 day later, my IP was banned. Outlook support said they cannot discuss the reason for the ban and will not unban it so I'm out of luck. I know I can just pay a provider $5/month and get email, but there is something about having full control over your own email. Is there anything much I can do?

It convinced itself there was some rewriting proxy in the webfetch tool. `Expires`, `trace` and `requestId` were consistent for a few requests, but they do change. `AccessKeyId` was always the same, "LTAI5t…QVZr" I did not add the `…` in the signature and access key. Probably training links, but that `Expires` number...
