Email dropped days later with "non DNSSEC destination" error
I sent an email to a domain that I have sent emails to before. TWO DAYS later I got an undeliverability notice with the error message "non DNSSEC destination". I'm now out more than €100 for not cancelling a contract on time. What a fucking joke! Seriously, mailbox, you cannot deliver service like this an expect people to use you for mission critical email.
