It’s a huge pain in the ass getting things like DMARC and DKIM and whatever to work. Without those, most providers won’t even deliver your messages. But luckily, there are websites that help you check and fix your configuration
Even once you do get these things set up correctly, most providers will send your outgoing messages straight to the recipient’s spam folder
That being said, I believe most providers will mark you as “not spam” if the other person initiates the conversation. So this could be a non-problem if you’re making an email for your business and putting it on business cards or something.
Mullvad (VPN provider) self-hosts their support email, and they seem to be doing fine.
Selfhosted email I guess.
Is that even feasible without getting marked as spam by all the major players?
Hi, I recently set up my own email server
Hope that helps
