Let's create your first mail account
password:
(again):

root@mail:/opt/mailinabox#

Nothing happened,after I enter the email address and password.

How can I find out where the problem is?

[kiekerjan]

Try sudo journalctl -u mailinabox
And you can "just" retry the installation, can´t hurt at this time.

Thanks @kiekerjan

any ideas?

[kiekerjan]

Not much to go on.
So where in time did you do the installation? Did you reboot it after installation? Does the admin panel work? What happens if you run the installation command again?

yes,I reboot it after installation,but the same error,services are not working.I ran the netstat and didn't see port 443 and 25
I'm going to recreate a new ubuntu 22.04 and then try it again.
Thanks again.
