In my account, no new emails show up since today, half past one.
It seems to work for other accounts, my wife still receives email.
There are no errors in carbonio.log, but logs of successful deliveries to my account, like this test mail I sent from Google, e.g.:

This looks to me like a completely successful delivery. But the email doesn't show up, neither in the web client nor in IMAP. I also tried exporting my inbox, the emails since half past one don't show up. There are several from different senders in logs.
The only thing I did at the time is creating another alias for my account (that was alias number 38), creating a persona with that alias in the account and sending an email with that persona. Since then, no more emails have arrived in my inbox. I have deleted both persona and alias now, but that didn't help.
I've also restarted Carbonio and even rebooted the whole server for good measure. Still no new mails in my inbox.
Help! I'm panicking! 🙁
Does anybody have an idea what the problem might be? Where I could look?
I found this in mailbox.log:
2024-01-21 17:56:43,530 INFO [LmtpServer-1] [name=xxx@xxx.net;mid=6;ip=123.456.789.123;] lmtp - accepted and discarded message from=xxx@gmail.com,to=xxx@xxx.net: local delivery is disabled
Which explains the behaviour, I guess, but why would local delivery be disabled for my account? And how?
Hm, zimbraPrefMailLocalDeliveryDisabled was set to TRUE for my account. I set it to false, and now I'm receiving emails again.
But how on earth did that happen? Any hints?
Hm, I think I may have accidently hit what is called "Keine lokale Kopie der Nachrichten speichern" (roughly "Don't save a local copy of the messages") in the German admin panel, in the forwarding settings of my user. At least I found that activating this switch will set zimbraPrefMailLocalDeliveryDisabled to TRUE.
Phew.
I had the same problem, thanks for the hint! No idea how this setting was activated (only on the first account, that was created).
