Likely the same issue but, the confirmation email is completely rejected by mailbox.org by default.
By default mailbox.org completely rejects email it considers spam. I thought I had it setup to put spam in the "Junk" folder but the settings are a bit tricky if you don't pay close attention to the FAQ here. If a "technical filter" (Greylisting, SMTP Plausibility check, Realtime Blacklist) is enabled, emails that match the technical filter will be *rejected* and not put in Junk, as the "move to Junk" option is only for the content filter. The confirmation email matches one of the technical filters, so I'm posting here in case it could help someone else who is wondering why it is not even in Junk ...
