@linuxcuba This is not log that i requested to you.
Errors that you paste here are only systemd unit errors, they doesn't work because mailbox is down.
Please inspect these logs :
/opt/zextras/log/mailbox.log /opt/zextras/log/zmmailboxd.out
If you need i can check the content for you, send me a private message with the compressed file.
On a separate but related note, I also ran into this issue when I could not send any email, and looking at `zmcontrol status` showed the service discovery not running. Doing a bit more digging I thought it might be related to an IP change I did recently when a server was moved to a new vlan.
I dug around and found this setting:
/etc/zextras/service-discover/config.json
Had:
{ "bind_addr": "10.140.1.10" }
Which was my old IP; updating that and restarting carbonio fixed my issue and service-discovery started working again.
