I've just upgraded Carbonio CE and OS, I mean:
Running Ubuntu server 22.04:
I've upgraded Carbonio CE from 25.9.0 to 25.12.0 and, apparently, it has gone well (following this https://docs.zextras.com/carbonio-ce/html/upgrade/upgrade.html).
After that I have proceeded to upgrade from Ubuntu 22.04 to 24.04 (following this https://docs.zextras.com/carbonio-ce/html/upgrade/toc.html).
Now I have Ubuntu 24.04 and Carbonio CE 25.12.0, but things are not running well:
Carbonio starts apparently well. Web user interface and web admin console are both accessible and calendar is also working. However, I can't receive any email (not even from an account on the server itself).
systemctl status carbonio-* shows all processes as active (running).
Any suggestions?
Thanks in advance and best regards.
I should mention that everything worked fine before the upgrades.
Carbonio server is behind a router/firewall with needed ports mapped.
Before upgrading /var/log/mail.log showed (being XX.XX.XX.XX the server static public IP).
Dec 21 17:17:47 postfix/smtps/smtpd[1986830]: connect from [XX.XX.XX.XX]
Dec 21 17:17:47 postfix/smtps/smtpd[1986830]: Anonymous TLS connection established from [XX.XX.XX.XX]: TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange x25519 server-signature ECDSA (prime256v1) server-digest SHA256
After the upgrades /var/log/mail.log shows:
postfix/error[28123]: 94F974D05F44: to=<usu@domain>, relay=none, delay=9202, delays=9202/0.02/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to server.name [XX.XX.XX.XX]:7025: Connection refused)
Being XX.XX.XX.XX the same server static public IP.
usu@domain -> not a real address
server.name -> not the real server name
At this point I'm feeling lost: I don't know the cause of this behavior after the upgrades.
Any help will be welcome.
Thank you so much.

Insert the cluster credential password:
There are no pending-setups to run. Exiting!
"zmprov ms mail.example.com zimbraMtaLmtpHostLookup native
zmprov mcf zimbraMtaLmtpHostLookup nativ"
This works!! And the server begins to receive mails.
So, may you, please, explain what do those two commands do? It's always great learning something new.
Thank you so much.
I found myself the explanation for those commands, here:
https://wiki.zimbra.com/wiki/Incoming_Mail_Problems
"There is no connection to port 7025 to perform Local Mail Transfer Protocol (LMTP) delivery.
This is nearly always caused by a host that is configured on private IP Space (or using NAT) and that does not have an interface for the public IP address the server resides on. This can be easily fixed by simply using native IP address lookups for lmtp rather than DNS."
However, I don't know/understand how this issue has happened after upgrading Ubuntu from 22.04 to 24.04. If anyone has any idea, it would be welcome...
Anyway, thanks for your trick and best regards.
I have a zimbra running behind NAT, and it helped me to add the public IP address to the looopback interface with netmask /32 e.g.: `ifconfig lo:1 xx.xx.xx.xx 255.255.255.255` So it may help on carbonio as well.
